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 of the Airbus A318 in 2003. In mid-April 2005, Frontier officially became an all-Airbus fleet, retiring its last Boeing 737.
Air travel is undoubtedly the fastest and the safest way to travel which opens up a market for several companies to become your preferred airlines. In such a scenario, when the passenger is literally spoilt for choice and can easily acquire the best deals easily, it sometimes ironically becomes difficult for one to choose any one airline amongst so many. This is why an airline which can make permanent customers out of first time fliers is the one that can actually survive. One such airline is the Allegiant Air.
Also in 2010, JetBlue entered into interline booking agreements with South African Airways and American Airlines to facilitate luggage transfers between airlines for passengers with connecting flights on a different carrier. The agreement with American included JetBlue's 18 destinations not served by American and American's 12 international flights out of New York–JFK and Boston Logan. In addition, American gave JetBlue 8 round trips slots out of Washington National in D.C. and 2 out of Westchester, New York. In return, JetBlue gave American 6 round trips out of New York–JFK. The agreement with American Airlines has since ended according to JetBlue's website.
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.
