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 October 2013, Republic Airways Holdings entered into an agreement with private equity firm Indigo Partners to sell Frontier Airlines for approximately $145 million. According to Indigo, the transaction would further Frontier's evolution into an ultra-low-cost carrier.[38] In December 2013, Indigo Partners LLC, through an affiliate, completed the purchase of Frontier Airlines from Republic Airways Holdings. The airline's headquarters will remain in Denver.[46] Republic Airways Holdings subsidiary Republic Airlines no longer flies Embraer 190 aircraft on behalf of Frontier, as of January 1, 2014.

On October 13, 2009, the airline unveiled a modification to its livery in commemoration of the upcoming 10th anniversary of the airline in February 2010. Besides a new tail design, the revised livery includes larger "billboard" titles extending down over the passenger windows at the front of the aircraft. The logo word 'jetBlue' will no longer be silver and blue but now a dark, navy blue.[40]

Following the February 2007 incident in which the airline was forced to cancel nearly 1,700 flights due to winter storms, jetBlue's board of directors replaced founder and Chief Executive Officer David Neeleman with Dave Barger.[21] He had politicked the board, while Neeleman was busy publicly apologizing. Barger's ascendancy caused widespread demoralization in the ranks.[22] He became JetBlue's new Chief Executive Officer on May 10, 2007.[23] Neeleman, the company's founder and largest individual investor, became a nonexecutive chairman as a result of the change.[24]
Frontier took delivery of its first Airbus aircraft (an A319) in 2001 and simultaneously launched with it DirecTV in-flight television along with a new company livery. Frontier Airlines was the launch customer[20] of the Airbus A318 in 2003. In mid-April 2005, Frontier officially became an all-Airbus fleet, retiring its last Boeing 737.[citation needed]
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
On June 22, 2009, Frontier Airlines announced that pending bankruptcy court approval, Republic Airways Holdings, the Indianapolis-based parent company of Republic Airlines, would acquire all assets of Frontier Airlines for the amount of $108 million. Thus, Frontier Airlines would become a wholly owned subsidiary of Republic.[26] However, 5 weeks later on July 30, Dallas-based Southwest Airlines announced that it would be making a competing bid of $113.6 million for Frontier with intentions to also operate Frontier as a wholly owned subsidiary, but that it would gradually fold Frontier resources into current Southwest operating assets.[citation needed]
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]
Flight attendants at the carrier voted to organize their workgroup under the Transport Workers Union of America in December 2010, citing scheduling concerns among other issues in their work rules and the airline's pilots elected to vote on whether to join the International Brotherhood of Teamsters in July 2012.[54] In August 2012, the pilots voted to organize and joined the Teamsters.[55] Allegiant's chairman and CEO, Maurice J. Gallagher Jr., has been critical of the unionization of airline employees, and has stated, "Unionization is one of those things that clogs the arteries and makes you less quick and not as nimble as you need to be on top of your game... In this industry and others that are heavily unionized, you ultimately end up with bankruptcy as the primary driver."[54]
Frontier Airlines is an American ultra low-cost carrier headquartered in Denver, Colorado. The eighth-largest commercial airline in the US, Frontier Airlines operates flights to over 100 destinations throughout the United States and six international destinations, and employs more than 3,000 air-travel professionals.[15] The carrier is a subsidiary and operating brand of Indigo Partners, LLC, and maintains a hub at Denver International Airport with numerous focus cities across the US. In August 2018, Frontier began connecting passengers with Mexican low-cost carrier Volaris under a codeshare agreement.[16]
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]

In February 2012, Frontier Airlines cut five nonstop routes from Milwaukee. This move "reduced Frontier's daily departing flights out of Mitchell International from 32 to 18," or 56%. Frontier announced further layoffs in conjunction with this route change: up to 446 Milwaukee-area employees were affected by the job cuts that occurred between April 15 and April 30, 2012.[37]
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]
The company had charter contracts with Caesars Entertainment to ferry customers to Caesars casino properties through Reno-Tahoe International Airport, Laughlin/Bullhead International Airport and Tunica Municipal Airport.[48] These contracts ended in December 2012 when Caesars Entertainment signed a new contract with Republic Airways to provide the charter service to Caesars properties in Atlantic City, New Jersey, Tunica, Mississippi and Laughlin, Nevada.[49] 

The airline tends to offer lower fares, which requires strict cost control.[33] Part of the airline's lower cost structure included operation of McDonnell Douglas MD-80 jets, which the airline can purchase and refurbish for as little as $4 million.[40] While the aircraft are less fuel-efficient than newer planes, Allegiant was able to purchase used MD-80s outright for one-tenth the cost of a new Boeing 737 although Allegiant has subsequently purchased used Boeing 757-200s, Airbus A319s and Airbus A320s.[13] (The 757s were acquired for its Hawaii service while the Airbus jets were beginning to replace MD-80 aircraft). As of November 2018, however, Allegiant no longer operates any MD-80 aircraft, relying instead on an all-Airbus fleet.[50] Given the low cost of ownership, Allegiant is able to operate its aircraft less (seven flight hours per day on average versus 13 hours per day at JetBlue Airways), which helps keep labor costs lower.[13] Overall, Allegiant operates with 35 full-time workers per plane compared to more than 50 at other carriers. Allegiant schedules their crew members so that they always return to their domicile at the end of the day, thus avoiding the need for hotel rooms which can be a costly expense for airlines.[40]
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 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 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.
As Republic Airways Holdings was in the process of bidding to acquire Frontier in 2009, it was also in the process of acquiring Milwaukee-based Midwest Airlines. Through the fall and winter of 2009, Republic operated its two new acquisitions as separate brands. However, to improve efficiency by better matching aircraft capacity to route demand, Republic began to intermix the fleets of the two airlines, swapping a portion of its higher-capacity planes from Frontier with its smaller-capacity planes from Midwest and vice versa. However, the move caused some confusion amongst the public, as the two brands did not offer the same amenities and did not match the amenities mentioned on the airfare. As a result, in the Spring of 2010, Frontier and Midwest Airlines announced that their brands would merge, with Frontier being the surviving brand.[33] This was a merger of brands only—no Midwest Airlines aircraft was ever operated by Frontier, as by this time, all Midwest Airlines flights were operated on its behalf by other Republic Airways Holdings subsidiaries.[citation needed]
According to Martin St. George, senior vice president of marketing and commercial strategy at jetBlue, the new "You Above All" campaign was created to get jetBlue back to their "DNA" and speak to the "core of who we are as a brand". This motto is meant to support their efforts to always put the customer first and "bring humanity back to air travel".[95]
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]
