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.[56] 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.[57]
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. 

jetBlue experienced its first-ever quarterly loss during the fourth quarter of 2005 when the airline lost $42.4 million, enough to make them unprofitable for the entire year of 2005. The loss was the airline's first since going public in 2002. JetBlue also reported a loss in the first quarter of 2006. In addition to that, jetBlue forecasted a loss for 2006, citing high fuel prices, operating inefficiency, and fleet costs. During the first quarter report, CEO David Neeleman, President Dave Barger, and then-CFO John Owen released JetBlue's "Return to Profitability" ("RTP") plan, stating in detail how they would curtail costs and improve revenue to regain profitability. The plan called for $50 million in annual cost cuts and a push to boost revenue by $30 million. jetBlue Airways moved out of the red during the second quarter of 2006, beating Wall Street expectations by announcing a net profit of $14 million. That result was flat when compared to jetBlue's results from the same quarter a year before ($13 million), but it was double Wall Street forecasts of a $7 million profit, Reuters reports. The carrier said cost-cutting and stronger revenue helped it offset higher jet fuel costs. In October 2006, jetBlue announced a net loss of $500,000 for Quarter 3, and a plan to regain that loss by deferring some of their E190 deliveries and by selling 5 of their A320s.[citation needed]
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]
jetBlue's first major advertising campaign incorporated phrases like "Unbelievable" and "We like you, too". Full-page newspaper advertisements boasted low fares, new aircraft, leather seats, spacious legroom, and a customer-service-oriented staff committed to "bringing humanity back to air travel".[92] With a goal of raising the bar for in-flight experience, jetBlue became the first airline to offer all passengers personalized in-flight entertainment. In April 2000, flat-screen monitors installed in every seatback allow customers live access to over 20 DirecTV channels at no additional cost.[93]

Frontier was ranked in an airline quality rating report by Embry-Riddle Aeronautical University and Wichita State University in 2015 as one of the five worst airlines in the United States, especially due to its rate of customer complaints and bumped passengers.[88][51][89] The airline also had relatively poor on-time performance, and the waiting time for help when calling the airline on the phone was reported to have risen to two hours or more.[90]

In September 2009, JetBlue made changes to its TrueBlue program.[132] In the new program, members receive three points for every dollar spent toward a flight, excluding taxes and fees, plus an additional three points for every dollar spent on a flight if booked online directly on the JetBlue.com website. Additional points are awarded if the member uses the Barclay's issued JetBlue Mastercard credit card to purchase the flight. The price of flights in points depend on the fare of the flight in U.S. dollars. The new program launched on November 9, 2009.[133][134]

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]

On March 19, 2008, jetBlue added Orlando, Florida as a gateway focus city to international destinations in the Caribbean, Mexico, and South America. New international routes from Orlando International Airport include Cancún, Mexico, Bridgetown, Barbados, Bogotá, Colombia, Nassau, Bahamas, San José, Costa Rica, and Santo Domingo, Dominican Republic. In conjunction with the addition of new routes the airline will continue significant expansion of operations at Orlando International Airport including a planned 292-room lodge that will house trainees attending the existing "JetBlue University" training facility (opened in 2015).[33]


On November 15, 2017 Frontier Airlines announced a $15 billion order for 134 additional A320neo family aircraft. The order, slightly revised under new owner Indigo, consists of 100 A320neo and 34 A321neo. The order also includes the conversion of the remaining A319neo to A320neo.[80] With this order, Frontier Airlines fleet has industry-leading fuel efficiency. The fleet is also one of the most modern and young, particularly in comparison to other low-cost carriers,[nt 1] at an average age of 5 years as of 2018.[81]
As part of its plan to stay competitive in reaction to the entry of Southwest Airlines into Denver, the company underwent a reorganization early in 2006. On April 3, 2006, Frontier created Frontier Airlines Holdings (FRNT), a holding company incorporated in Delaware to take advantage of favorable tax laws in that state. The corporate headquarters did not leave Colorado.[21]
On December 13, 2007, jetBlue and Germany-based Lufthansa announced jetBlue's intent to sell 19% of jetBlue to Lufthansa, pending approval from US regulators. Following the acquisition, Lufthansa stated they plan to seek operational cooperation with jetBlue.[30] Lufthansa plans to offer connections to JetBlue flights in Boston, New York (JFK), and Orlando International Airport (no longer a connection).[31]

On August 4, 2008, the Associated Press reported that jetBlue would replace their recycled pillows and blankets with an "eco-friendly" pillow and blanket package that passengers would have to purchase for use. Each package will cost $7 and will include a $5 coupon from retailer Bed, Bath and Beyond. This decision is the latest in a series of moves designed to increase revenue. jetBlue told the Associated Press that it expects to collect $40 million from passengers selecting seats with extra legroom and $20 million from passengers paying $15 to check a second bag. As of September 8, 2008 JetBlue charges passengers $10–30 for an extended-leg-room seat depending on the length of the flight.[37]
After making a codeshare agreement with Lufthansa that went into effect in 2010, jetBlue transitioned to the Sabre reservation system used by Lufthansa,[107] enabling the airlines to sell tickets on each other's flights, transfer luggage and passengers between the two carriers, and combine frequent flyer programs,.[108] By making use of JetBlue's North America routes as a feeder network, the agreement put Lufthansa in a position to operate quasi-hubs in New York–JFK and Boston Logan.
