In July 2012, Allegiant announced the future addition of the Airbus A319-100 aircraft to its fleet. The aircraft are used and formerly belonged to easyJet and Cebu Pacific. All of them are high-density A319s, fitted with four overwing exits, allowing 156 seats. Two former easyJet aircraft entered service in 2013, with another in 2014 and an additional six in 2015.[75] In December 2012, Allegiant cancelled the agreement with Cebu Pacific citing an inability to agree on economic provisions.[76] On May 1, 2013, Allegiant purchased another A319 aircraft previously operated by easyJet that would enter service in the third quarter of 2013.[77] On February 23, 2015, Allegiant purchased six more A319s from Cebu Pacific.[78]
Allegiant aims primarily to serve leisure travelers, particularly those in colder northern climates, going to warm-weather tourist destinations such as Punta Gorda, Tampa Bay, Las Vegas, Orlando, Los Angeles and Phoenix.[32] It also serves smaller destinations that see few direct flights by major carriers. Many of the airline's markets, such as Peoria, Illinois, are served only by commuter service requiring a connection at an airline hub.[33] In October 2009, Allegiant had competition on just five of its 136 routes.[34]
Frontier Airlines was incorporated on February 8, 1994, by a group that included executives of the original incarnation of Frontier Airlines in response to the void left by Continental Airlines' 1993 shutdown of its Denver (Stapleton) hub.[17] Scheduled flights began five months later in July 1994 using Boeing 737-200 jetliners on routes between Denver and four destinations in North Dakota: Bismarck, Minot, Fargo and Grand Forks. By January 1995, Frontier had expanded its route network from Denver and was serving Albuquerque, New Mexico; Billings, Montana; Bismarck, N.D.; Bozeman, Montana; El Paso, Texas; Fargo, N.D.; Great Falls, Montana; Las Vegas, Nevada; Missoula, Montana; Omaha, Nebraska; and Tucson, Arizona with 737's.[18] Like the original airline of the same name, the new Frontier operated a hub at Denver (DEN) and for the first nine years used the slogan "The Spirit of the West" which was displayed above the windows and just behind the cursive letters "Frontier" on the fuselage of their aircraft. In 1999, Frontier signed agreements to begin purchasing and leasing Airbus A318 and A319 jet aircraft and had also added Boeing 737-300 jetliners to its fleet as well. Also by September 1999, the airline was serving destinations from coast to coast in the U.S., having expanded its route network to include Atlanta (ATL); Baltimore (BWI); Bloomington/Normal, Illinois (BMI); Boston (BOS); Chicago (MDW, Midway Airport); Dallas/Fort Worth (DFW); Phoenix (PHX); Los Angeles (LAX); Minneapolis/St. Paul (MSP); New York City (LGA, LaGuardia Airport); Orlando (MCO); Portland, Oregon (PDX); Salt Lake City (SLC); San Diego (SAN); San Francisco (SFO); and Seattle (SEA), all served from its Denver hub.[19] 

On April 10, 2008, Frontier filed for Chapter 11 bankruptcy in reaction to the intent of its credit card processor, First Data, to withhold significant proceeds from ticket sales.[23][better source needed] First Data decided that it would withhold 100% of the carrier's proceeds from ticket sales beginning May 1.[24] According to Frontier's press release, "This change in practice would have represented a material change to our cash forecasts and business plan. Unchecked, it would have put severe restraints on Frontier's liquidity..." Its operation continued uninterrupted, though, as Chapter 11 bankruptcy protected the corporation's assets and allowed restructuring to ensure long-term viability.[citation needed] After months of losses, Frontier Airlines reported that they made their first profit during the month of November 2008, reporting US$2.9 million in net income for the month.[25]
In October 2013, jetBlue introduced Mint, a premium cabin service on transcontinental and select Caribbean flights. The service began in 2014, using the Airbus A321-231 aircraft ordered by jetBlue. These planes are outfitted with winglets, as well as with "lie flat" seats, and moveable partitions that can create small suites on the airplane.[56] Called "Mint" by jetBlue, these planes are configured with 16 business-class seats and 143 economy seats, instead of an all-economy configuration of 190 seats.[57]
Although it does not fly to Canada, Allegiant advertises extensively there and flies from about a dozen small airports near the Canada–US border. Many of its customers at airports such as Bellingham, Washington (BLI), Niagara Falls, New York (IAG), Ogdensburg, New York (OGS), Grand Forks, North Dakota (GFK) and Plattsburgh, New York (PBG) are Canadians, who can save money by flying from U.S. airports.[35]

After booking a excursion in St Maarten that never happened as the companies website and phone number were taken down so no final arrangements could be made. Called travelocity twice and still can not seem to get it through their heads about the service not happening. They tried contacting the company....no luck then they asked me for the contact information I had.....are you kidding me it is your contracted service (IDIOTS)....anyway none of my contact info worked for the company why badger me.....just give me my refund. I will post followups as they happen 

While its financial performance started showing signs of improvement, in February 2007, jetBlue faced a crisis, when a snowstorm hit the Northeast and Midwest, throwing the airline's operations into chaos. Because jetBlue followed the practice of never cancelling flights, it desisted from calling flights off, even when the ice storm hit and the airline was forced to keep several planes on the ground. Because of this, passengers were kept waiting at the airports for their flights to take off. In some cases, passengers who had already boarded their planes were kept waiting on the apron for several hours and were not allowed to disembark. However, after all this, the airline was eventually forced to cancel most of its flights because of prevailing weather conditions.[17] The fiasco reportedly cost JetBlue $30 million.[18]
Allegiant Air has been closely monitored by the FAA due to many emergency landings and aborted takeoffs.[56] ABC interviewed a former Allegiant mechanic, who said "Dedicated steps were not being performed with maintenance manuals or even with general practices, before an aircraft is released."[57] Many of these incidents had involved Allegiant's aging MD-80 aircraft, which as of November 2018 have been replaced by newer Airbus A320 family aircraft.[58][50] 46 of the 86 aircraft have made emergency landings, all of which were on MD-80s.[59] The average age of Allegiant's MD-80 fleet was 29 years compared to less than 13 years for its Airbus fleet.[58]
On October 25, 2007, the airline opened a fourth focus city and operations base at Phoenix-Mesa Gateway Airport in Mesa, Arizona, connecting 13 cities already served by Allegiant and one new city to the Phoenix metropolitan area.[17] The airport announced a 10,000-square-foot (930 m2) expansion in August 2008, which increased the number of gates from two to four and allowed Allegiant to triple the number of flights from Phoenix. The expansion was funded by a loan from Allegiant which will be repaid by passenger fees.[18]
In July 2017, Frontier announced 21 new cities and 84 new routes. These cities include Buffalo, Charleston, S.C., Pensacola, Jackson Hole, Palm Springs, San Jose, Reno, Little Rock, and Tulsa. Destinations that saw a significant bump-up in new service include Austin, Cincinnati, Long Island/Islip, N.Y., Miami, Orlando, Providence, San Antonio, and Tampa.[68]

In May 2017, Allegiant Air took delivery of its first brand-new A320. Allegiant took delivery of ten new A320s in 2017 and is scheduled to accept two in 2018. All new aircraft will be painted in Allegiant's new livery at the time it is delivered. Older Airbus aircraft will be repainted during their C-checks.[83] The new Airbus aircraft will have fuel-efficient sharklets. The new A320s seat 186 passengers, an increase of the 177 seats that are found in the rest of the Allegiant A320 fleet. To fit the additional nine seats, Allegiant opted for the Airbus Space-Flex V2 Lavatory. [84]
The flight personnel and cabin crew where not friendly at all and continuously knocked my shoulders (which where wider than the sear backs) every time they came by and hit my right leg which I had placed on the outside of the seat in front of me as I had a brace on that leg and did say excuse me or I’m sorry the whole time that they hit my leg or my shoulder. By the way and I didn’t tell them but I have undergone reverse shoulder surgery on both of my shoulders/arms and I really don’t expect to get hit every time they pass me

Animal concepts used in the livery extend into Frontier's marketing as well. Each animal has a specific name.[87] Animal aircraft used in their radio and television commercials include Jack the rabbit, Grizwald the bear, Foxy the fox (for whom Jack has a crush), Flip the dolphin (who always gets stuck going to Chicago rather than the warmer climates the others are going to), Larry the lynx, Hector the sea otter, and Sal the cougar. New additions are Penguins Jim, Joe, Jay, and Gary, a barbershop-style quartet, singing the praises of EarlyReturns to an audience of Frontier's well-known characters from the "a whole different animal" campaign, Hector the otter, advertising Frontier's expanding service to Mexico, and Polly the Parrot, who won the new animal audition in 2012.
Allegiant also transports firefighters for the United States Forest Service as well as college basketball teams.[44] Allegiant had a contract to supply charter flights from Miami to four cities in Cuba beginning June 2009. One aircraft was committed to the contract.[44] The contract was for fixed-fee flying, meaning all the airline was required to do was provide the dry aircraft and the flight crew. The contractor was responsible for all other costs including fuel. However, Allegiant ended this service in August 2009.[47]

The TWA Hotel is the TWA Flight Center structure currently being rebuilt as 505-room hotel, preserving the Eero Saarinen headhouse while replacing the structures on either side of the headhouse. Situated in front of JetBlue's JFK terminal, JetBlue has stated that it estimates the ownership of the hotel would be between 5–10% of the final total investment.[138] The hotel will be an effective replacement for the Ramada Plaza JFK Hotel on the north end of the airport grounds in Building 144, which closed in 2009.
In July 2016, jetBlue announced commercial flights from the United States to Cuba will commence in late August.[64][65] On August 31, 2016, JetBlue Flight 387 from Fort Lauderdale–Hollywood International Airport to Abel Santamaría Airport, in Santa Clara, became the first scheduled commercial flight between the United States and Cuba in 55 years.[66] Only charter flights were allowed under previous rules, which required that passengers had to arrive more than 4 hours before the scheduled departure and often endure long lines for documentation checks, late flight arrivals, and pay high baggage fees.[67] 

jetBlue previously had its headquarters at 80–02 Kew Gardens Road,[80] and then in the Forest Hills Tower, both in Forest Hills, Queens, New York City,[81][80] 6 miles (9.7 km) from the current office in Long Island City.[82] In 2001 the airline had announced that it wanted to take 74,000 square feet (6,900 m2) of space in the Forest Hills Tower, and by December 2002 announced that it planned to increase its leased space.
jetBlue expanded service to the Caribbean, including to St. Maarten and Puerto Plata commencing January 10, 2008. With these additional destinations, jetBlue serves a total of twelve Caribbean/Atlantic destinations including Aruba; Barbados; Bermuda; Cancún; Nassau; Aguadilla; Ponce; San Juan, Puerto Rico; Santiago; and Santo Domingo, Dominican Republic.[citation needed]
On July 24, 2007, jetBlue reported that its second-quarter revenue increased to $730 million, compared to $612 in 2006. Second quarter net income grew to $21 million for the quarter, from $14 million the previous year. CEO David Barger said the airline will take delivery of three fewer planes this year and will sell three planes from their current fleet, "slowing capacity growth ... to strengthen our balance sheet and facilitate earnings growth", but will continue to add two to four new destinations each year.[25]
On October 25, 2016 JetSuiteX announced that JetBlue had made a minority equity investment in JetSuiteX. Part of the agreement also gave JetBlue a seat on JetSuite's board of directors. Reasons for the investment was outlined by CEO Robin Hayes "Our investment in JetSuite makes sense as we continue to execute on our west coast plan and invest in innovative ideas that reflect the disruptive spirit of JetBlue."[143] In JetBlue's 1st quarter 2018 investor call JetBlue's CFO Steven Priest Confirmed they currently hold about 10% [144] of JetSuiteX.
Frontier has a three-tier frequent flyer status program. The tiers are Elite 20K (earned by flying 20,000 Status Qualifying Miles [SQM] or 25 segments in a calendar year), Elite 50K (50,000 SQM or 50 segments), and Elite 100K (100,000 SQM or 100 segments). Elite benefits include free carry-on and checked bags, advance seat assignment and family seating, priority boarding, redemption fee waiver, stretch seating, Discount Den membership, and mileage multipliers.[74]
In 2011, JetBlue made interline agreements with Virgin Atlantic and Jet Airways, both of which have since been terminated.[112][113] Since 2012, JetBlue has had an interlining agreement with Air China. It also established an interline agreement with Porter Airlines connecting from Billy Bishop Toronto City Airport to US destinations through Boston and Newark.[114]
In an effort to focus on regional contract flights for major carriers, Republic Airways Holdings announced in January 2012 its intention to sell or spin off Frontier.[38][39] On January 26, 2012, Republic Airways Holdings appointed former US Airways and Gate Gourmet CEO David Siegel as President and CEO of Frontier Airlines. Republic also added new senior officers for Frontier's finance and commercial team, among other changes in the executive leadership team. Siegel and other Frontier executives moved to Denver where Frontier is headquartered in order to facilitate management of all aspects of Frontier during its separation process from Republic and continue its transformation into an ultra-low-cost carrier.[13]
Allegiant also earns commissions by offering hotel rooms, car rentals and admission to tourist attractions on its website. It sells package vacations under the brand name Allegiant Vacations. The company has arrangements with 34 hotels in Las Vegas and 21 in the Orlando and Daytona Beach, Florida, areas. In 2008, the airline sold 400,000 hotel room nights.[42] Commissions on hotel and rental car packages are up to one-third of the airline's revenue.[40][42]

I was a frontier fly club member for a whole year and found that their website was way to confusing to use. They would advertise a promotion but then when I clicked it and would attempt to purchase the travel itinerary it would always go up. It was disappointing. Specially because I paid a membership fee and wanted to travel. Customer service over the phone was no help. Wouldn’t do it again. Stopped flying with them over all.
In 2009, jetBlue announced that it was looking for a new headquarters location, and was considering moving either within the New York City metropolitan area or to the Orlando, Florida area.[83] In April 2009, Helen Marshall, the president of the Borough of Queens, said that the City of New York was trying to keep JetBlue in the city;[84] in January 2010, the CEO of JetBlue, Dave Barger, and Governor of Florida Charlie Crist met in Tallahassee, Florida to discuss a possible move to Orlando.[85] A decision was expected by March 2010,[86] although a move would not happen until 2012, when its lease in the Forest Hills Tower expired.[87]
On December 13, 2007, jetBlue and Germany-based Lufthansa announced jetBlue's intent to sell 19% of jetBlue to Lufthansa, pending approval from US regulators. Following the acquisition, Lufthansa stated they plan to seek operational cooperation with jetBlue.[30] Lufthansa plans to offer connections to JetBlue flights in Boston, New York (JFK), and Orlando International Airport (no longer a connection).[31]
Allegiant also transports firefighters for the United States Forest Service as well as college basketball teams.[44] Allegiant had a contract to supply charter flights from Miami to four cities in Cuba beginning June 2009. One aircraft was committed to the contract.[44] The contract was for fixed-fee flying, meaning all the airline was required to do was provide the dry aircraft and the flight crew. The contractor was responsible for all other costs including fuel. However, Allegiant ended this service in August 2009.[47]
Buyer beware! Do not use this service! I booked a trip for my son and then needed to change the reservation the next day. The customer service person said to cancel the first trip and "re book the whole reservation again (my son needed to stay 2 extra days). A partial refund came in 2 days later for the cost of the hotel. The refund was short $500.00 for the airfare. I called after about 6 days and was told it was being processed and would take up to 7 days. I called 5 days later (day 11) and was told it was processed and the hold up was on the part of my bank. I called the bank who had no record of this at all. They are now disputing the charges with Travelocity. It's been a time consuming and aggravating nightmare. Be aware and careful before you use Travelocity. In looking at their reviews this is not an isolated instance. They seem to have very poor business practices throughout!

Frontier was ranked in an airline quality rating report by Embry-Riddle Aeronautical University and Wichita State University in 2015 as one of the five worst airlines in the United States, especially due to its rate of customer complaints and bumped passengers.[88][51][89] The airline also had relatively poor on-time performance, and the waiting time for help when calling the airline on the phone was reported to have risen to two hours or more.[90]

In February 2011, Allegiant proposed to sell two types of tickets to passengers: advance tickets at a fixed higher rate and time-of-departure tickets that cost less but may have fees added based on the price of aviation fuel.[37] In 2012, the U.S. Department of Transportation banned the practice as part of wider regulations that also require taxes and fees to be included in airfares. Allegiant, along with Spirit Airlines and Southwest Airlines, sued the DOT to overturn these new rules. The United States Court of Appeals for the District of Columbia Circuit ruled in favor of the DOT on 24 July 2012[38] and the US Supreme Court denied certiorari on 1 April 2013.[39]
In 2014, Frontier announced it would be transitioning into an ultra-low cost carrier.[47] Frontier will also cut several flights and jobs at their Denver hub and transition them to different markets. On January 16, 2015 Frontier announced that it will close both its Denver and Milwaukee call centers, laying off 1,300 employees and outsourcing the jobs to call center company, Sitel, which operates a large call center for Frontier in Las Cruces, New Mexico.[48] As part of its transition to an ultra-low-cost airline, Frontier Airlines joined Spirit and Allegiant in June 2015 in removing its toll-free telephone number for customer service.[49]

In summer 2015, a rash of midair breakdowns drew federal scrutiny. "Before the night was finished on June 25, 2015, five Allegiant flights had been interrupted in four hours, all because different planes had failed in midair," reported the Tampa Bay Times.[28] Since October 2015, the Federal Aviation Administration has kept Allegiant under close supervision.[29][30][31] In July 2015, Allegiant Air announced bases would be established at the Asheville Regional Airport and Cincinnati/Northern Kentucky International Airport, becoming the first base at a non-vacation destination.[citation needed]
Made a reservation for a one night hotel stay at Days Inn & Suites Wyndham Bentonville, Arkansas. Ten minutes later attempted to cancel reservation due to error in date. Travelocity responded with they would need to contact Days Inn to inquire about a refund on my behalf. Subsequently, shortly thereafter, received an email from Travelocity stating they were unable to give me a refund due to Days Inn's inability and refusal to refund. I contacted Days Inn personally and they denied this claim, stating it was Travelocity that I had paid and they are the ones who would need to refund me. You do not get good business by deception. I DO NOT recommend them and WILL NEVER use again. Be cautious.

On January 11, 2007, Frontier Airlines signed an 11-year service agreement with Republic Airlines. Under the agreement, Republic was to operate 17, 76-seat Embraer 170 aircraft for the former Frontier JetExpress operations. At the time the contract was canceled in April 2008, Republic Airlines operated 11 aircraft for Frontier Airlines, with the remaining six aircraft expected to join the fleet by December 2008. With the integration of Republic aircraft, the 'JetExpress' denotation was removed. Subsequent to the cessation of Horizon's services for Frontier in December 2007, all flights operated by Republic were sold and marketed as "Frontier Airlines, operated by Republic Airlines." The first market created specifically for the Embraer 170 was Louisville, Kentucky, which began on April 1, 2007. Service to Louisville was suspended in August 2008 but restarted in April 2010.[citation needed]
We arrived at the airport at 5:15 for our 7:15 flight. After two delays we received a text message from the company that the flight had been canceled. 35 minutes later an employee finally came out to announce the cancellation. As we started asking questions like “will we get our money back” or “do you have any more flights going out we can get on” each time a piece of paper was picked up and shaken in our faces and were told to read the paper just like everyone else. Worst service ever!!!!!! We were all states away from home with no where to go and no help from frontier. And our refund could be expected within two weeks. All I could think of is how I hoped everyone there could find funds to purchase another ticket to where they were going. Because last minute tickets are crazy expensive. I will never fly frontier again!!!! They gave me a $100 voucher off my next flight with them but I’ll never use it!!!

In 2008, jetBlue partnered with Irish flagship carrier Aer Lingus to allow passengers to switch between airlines on a single ticket for flights with connections in New York–JFK or Boston Logan. Unlike traditional codeshare agreements, the companies cannot sell seats on each other's flights, so customers initiate the purchase on one airline's website and then are transferred to the other site to complete the transaction.[105][106]
JetBlue Technology Ventures (JTV) [137] is a wholly owned subsidiary of JetBlue that was established in February 2016.[138] JTV is the venture capital arm of JetBlue that invests in and partners with early-stage startups in the travel, hospitality, and transportation space. Its mission is to improve the end-to-end experience of travelers everywhere. As of November 2018, JTV has invested in 21 startups, including hybrid planes,[139] machine learning algorithms,[140] and ground transportation.[141] Investments range in size from $250,000 to $1 million.[142]

September 21, 2005: Flight 292 en route from Burbank, California, to New York City performed an emergency landing at Los Angeles International Airport (pictured on the right) following a failure of the front landing gear during retraction when it turned 90 degrees. The plane landed after holding for about three hours to burn fuel and therefore lighten the aircraft. The aircraft came to a stop without incident on runway 25L, the second-longest runway at LAX. The only apparent damage to the plane upon landing was the destruction of the front wheels, which were ground down to almost semicircles, and the tires; the front landing strut held. The passengers were unable to see themselves landing despite the DirecTV service in each seat, as they were instructed to brace.[147]

A November 2016 analysis by the Tampa Bay Times noted that Allegiant's planes were four times more likely to have in-flight failures than other major US airlines.[64] A 60 Minutes report by CBS News in 2018 continued to investigate the issues first raised by the Tampa Bay Times.[65] Public records cited in the investigation found that the airline had more than 100 serious mechanical incidents between January 1, 2016 and October 31, 2017, including "mid-air engine failures, smoke and fumes in the cabin, rapid descents, flight control malfunctions, hydraulic leaks and aborted takeoffs."[65] Other public records further revealed that Allegiant aircraft, on average, were nearly three and a half times more likely to have mid-air breakdowns than American, United, Delta, JetBlue and Spirit.[65]
