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]
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]
On October 22, 2008, jetBlue opened its new primary hub at John F. Kennedy International Airport (JFK), Terminal 5, or simply T5. The mostly new terminal, costing approximately $800 million,[41] partially encircles the historic TWA Flight Center, the former Trans World Airlines terminal designed by Eero Saarinen, which remains closed. According to the plan, passengers will eventually be able to check in for flights in the landmark building, then transfer to the new structure via the original passenger departing-arrival tubes from Saarinen's original terminal and its 1969 addition by Roche-Dinkeloo.[42]
Frequent flyers of jetBlue Airways can benefit from the airline�s loyalty program, TrueBlue. The carrier takes a high-tech approach to their "flight gratitude program," skipping membership cards and paper mailings in favor of online operations. Points earned through jetBlue or its partners do not expire, as long as the member flies with the airline at least once per year. Points are earned for flights booked, with members accumulating three points for every dollar spent on a jetBlue service. The carrier awards double points if members book online.
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.

As of 2018 it ranked No. 402 financially on the Fortune 500 list of the largest United States corporations by total revenue.[8] JetBlue Airways operates over 1,000 flights daily[9] and serves 102[10] domestic and international network destinations in the U.S., Mexico, the Caribbean, Central America and South America. JetBlue is not a member of any of the three major airline alliances, but it has codeshare agreements with 21 airlines, including member airlines of oneworld, SkyTeam, Star Alliance, and unaffiliated airlines.

In the March edition of Airways Magazine, it was announced that once jetBlue partnered with Yahoo! and with BlackBerry producer Research in Motion, that the airline would offer free, limited Wi-Fi capabilities on a single aircraft, N651JB, an Airbus A320-232 dubbed "BetaBlue". People access e-mail with a Wi-Fi capable Blackberry, or use Yahoo!'s e-mail and instant messaging with a Wi-Fi capable laptop, while in flight over the US. LiveTV in Melbourne Florida, created and operated the "BetaBlue" prototype. The "BetaBlue" system utilized the bandwidth and infrastructure of defunct Airfone.[32]

On September 9, 2014, Frontier introduced an updated livery,[86] as part of a rebranding that saw the spokesanimals' roles increase. The new livery reintroduced a green "FRONTIER" typeface to the fuselage, featuring the stylized "F" designed by Saul Bass for the original Frontier in 1978. Each aircraft features the name of the animal featured on its tail near the nose of the aircraft for easier identification. Currently about twenty five aircraft in the Frontier fleet feature the new livery.

In 2007, jetBlue was also facing reliability problems with its Embraer 190 fleet. For a couple of months, jetBlue contracted ExpressJet to operate four Embraer 145 regional jets on behalf of jetBlue. While this was going on two E-190 aircraft at a time were sent to an Embraer maintenance facility in Nashville, Tennessee.[19] ExpressJet operated routes between Boston Logan and Buffalo, New York and Washington Dulles, and between New York–JFK and Columbus, Ohio (has terminated) and Richmond, Virginia.[20]
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]

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]
Nevada-based Allegiant (G4) is a low-cost carrier that flies all Economy Class aircraft to about 100 destinations in 40 US states. On many routes, it only operates a couple times a week, and it typically flies to smaller, regional airports. However, Allegiant's focus cities include a mix of smaller and larger airports, including Bellingham International Airport (BLI), Fort Lauderdale–Hollywood International Airport (FLL), Los Angeles International Airport (LAX), Las Vegas's McCarran International Airport (LAS) and Phoenix–Mesa Gateway Airport (AZA).

On March 22, 2010, jetBlue announced it would remain in the New York City area, in Long Island City,[88] because of the airline's historical links to the city, the cost of staff relocations, the airline's desire to retain access to financial markets, and because Aer Lingus and Lufthansa, jetBlue's marketing partners, fly into JFK Airport.[89] jetBlue planned to combine its Forest Hills and Darien, Connecticut offices, together about 1,000 employees, into about 200,000 square feet (19,000 m2) in the Brewster Building by mid-2012.[90]
