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.
In July 2012, the U.S. Department of Transportation fined Travelocity $180,000 after discovering that Travelocity's “flexible dates tool” did not always include fuel surcharges that were part of many international airfares in violation of the Department's rules requiring all carrier-imposed surcharges and fees to be included in every advertised fare. In addition, the DOT found that the customer was informed only on the final page before purchasing the ticket that some itineraries required a paper ticket with a minimum additional delivery fee of $29.95.

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%.

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.
In 2011, JetBlue made interline agreements with Virgin Atlantic and Jet Airways, both of which have since been terminated. Since 2012, JetBlue has had an interlining agreement with Air China.

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. 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.
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. 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.
In July 2016, jetBlue announced commercial flights from the United States to Cuba will commence in late August. 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. 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.
