In December 2016, a winter weather event disrupted fleet operations, causing Frontier to delay or cancel up to 70% of their flights during the peak of the crisis, many without any advance notice. On the weekend of December 17, the storm caused major delays at Frontier's Denver hub, and the effects of the storm were felt throughout the fleet.[59] Flights were delayed or canceled at airports across the country, as in some cases, planes were ready to depart, but there were no rested flight crews available to service the flight.[60] The head of Frontier's pilot's union issued a statement criticizing the companies' handling of the event, comparing the airline to a "house of cards".[61] Frontier received over 30,000 refund requests for canceled flights resulting from the event.[citation needed]
In August 2017, Allegiant announced a new base would be established at the Indianapolis International Airport. The base began operations in early 2018. In February 2018, Allegiant also announced a new base would be established at the Destin–Fort Walton Beach Airport. In June 2018, Allegiant added another base at McGhee Tyson Airport in Knoxville, Tennessee. In January 2019, Allegiant announced they would be adding another base at Gerald R. Ford International Airport in Grand Rapids, Michigan.
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] 

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]
In 1997, Maverick Airways was operating code share service for Frontier with de Havilland Canada DHC-7 Dash 7 STOL capable turboprops between Denver (DEN) and two destinations in Colorado: Grand Junction (GJT) and Steamboat Springs (SBS).[66] However, the service was short lived as Maverick encountered financial challenges and then ceased all flights.
That's why I decided to use it again for our Rosarito getaway on Labor Day weekend. Found a less than fancy hotel at an amazing price of $53, taxes and breakfast included.  It was perfect for our needs, as we were only staying one night, and sleep only for a few hours at that. I ignored all the bad reviews of the hotel being dirty and unsafe, but I never imagined that so much worse awaited us. When we arrived, they told us that they were full and that there was no record of our reservation to begin with. How did that even happen? And if the hotel had been full since Friday, how did it allow me to do the reservation on Thursday? I couldn't reach them in Mexico. By the time I was able to talk to someone we were already in the United States and unable to take an alternative room. We only had one night, I didn't want to waste it looking for hotels when we had already checked two others at a way higher price. The only reason we went out there is for the amazing advertised price, the price I thought we had locked in through a reservation. But no way was I going to fall in that game of taking a more expensive room out of desperation. We just left. Drove back all the way to L.A.

Dave Siegel took the chief executive officer role in January 2012.[62] Siegel's tenure ran through May 2015, when he left for personal reasons and was succeeded by the company's chairman, Bill Franke, who would manage strategy and finances.[62] In April 2014, Barry L. Biffle was appointed as the company's president, reporting to Siegel;[63] after Siegel's departure, Biffle was charged with managing the company's day-to-day operations.[62]
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]

In February 2002, the airline launched its first regional product, Frontier JetExpress, initially operated by Mesa Airlines using CRJ-200 regional jets. Similar to "express" operations of other carriers, Frontier JetExpress was targeted for markets to and from Denver that do not generate traffic sufficient to support Frontier's smallest mainline jet, the Airbus A318, but could still offer lucrative business with a smaller jet.
In 2013, Allegiant acquired nine Airbus A320-200 aircraft from Spanish flag carrier Iberia.[79][80] Seven of the A320s were delivered in 2013 and were used for growth into new markets, including destinations in Mexico and the Rocky Mountains, as well as airfields such as Charlottesville and Shenandoah Valley in Virginia and Trenton, New Jersey.[76] On February 24, 2015, Allegiant announced the purchase of 2 additional A320s from Philippine Airlines which entered into service in 2015.[81] Later in 2015, the airline announced a firm order for an Airbus A320 direct from Airbus, the first time it has purchased new aircraft from the supplier.[82]

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]

JetBlue's in-flight options consist of gate-to-gate Fly-Fi service, offering over one hundred channels of DIRECTV, Sirius XM Radio, and movies, and on the Airbus A321, a 15″ interactive video screen which is not available on the rest of the fleet. JetBlue's partnership with Amazon lets customers watch Amazon Prime videos by connecting to Wi-Fi and downloading the Amazon Video app on their mobile phone or tablet. The in-flight WiFi under the "Fly-Fi" network is complimentary on all flights, at speeds of 12–15 megabits per second.
In January 2008, Allegiant opened its sixth base at Washington's Bellingham International Airport. The airline bases two McDonnell Douglas MD-80 aircraft in Bellingham as part of the expansion.[19] Routes served exclusively from Bellingham include Las Vegas, Palm Springs, San Diego, San Francisco and Phoenix. Expansion in Bellingham has been largely driven by its proximity to Greater Vancouver, British Columbia.

In March 22, 2010, jetBlue turned down incentives from the City of Orlando and announced its headquarters would keep its Forest Hills office,[46][47][48][49] start leasing and using a new office in the Brewster Building in Long Island City, New York.[50][51] in Queens Plaza in Long Island City,[49] move its headquarters there in mid-2012,[52] and start a joint branding deal with New York State using the iconic I Love NY logo.[49]
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]

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 March 2011, Allegiant took over charter service to Wendover Airport for Peppermill Casinos, Inc. to shuttle customers to Peppermill's three casinos in West Wendover, Nevada; the Montego Bay Resort, the Rainbow Wendover and the Peppermill Wendover.[45] Allegiant based one 150-seat, MD-80 series jet aircraft in Wendover and more than 20 employees, including maintenance, flight crews and stations personnel.[46]
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.
In July 2013, Frontier started service from New Castle Airport near Wilmington, Delaware to five destinations,[41] which Frontier markets as Wilmington/Philadelphia. Again, this airport had no commercial service prior to Frontier's entry.[citation needed] New Castle Airport lies roughly 30 miles southwest of Philadelphia International Airport and 75 miles northeast of Baltimore–Washington International Airport.[citation needed]

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]
