In April 2013, Frontier introduced a modified version of that livery, keeping the iconic animals on aircraft tails, but dropping its former slogan and replacing "FRONTIER" with "FLYFRONTIER.COM", the company's website, in support of new marketing that focused heavily on the airline's web presence. This livery was only painted on a few newly delivered aircraft. Aircraft in the older livery received "FLYFRONTIER.COM" titles on engine nacelles.

In December 2006, jetBlue, as part of their RTP plan, removed a row of seats from their A320s to lighten the aircraft by 904 lb (410 kg) and reduce the cabin crew size from four to three (per FAA regulation requiring one flight attendant per 50 seats), thus offsetting the lost revenue from the removal of seats, and further lightening the aircraft, resulting in less fuel burned.
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. 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.
In February 2015, Frontier announced that they will begin service to several destinations from Atlanta adding the airport as a focus city. In July, Frontier also began decreasing service from Washington Dulles International Airport removing the airport as a focus city. In early 2016 Frontier announced major route expansion from airports nationwide including Atlanta, Chicago, Cincinnati, Cleveland, Orlando, and Philadelphia. In June 2016, Frontier re-established service to Port Columbus International Airport. In May 2017, the airline announced opening a new crew base in Las Vegas in the fall 2017 to improve operational reliability and potentially create new jobs in Las Vegas. In December 2017, Frontier began service to Buffalo, New York, with service to Denver, Colorado, and Florida, including Miami, Fort Myers, Orlando, and Tampa.
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.
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.[better source needed] First Data decided that it would withhold 100% of the carrier's proceeds from ticket sales beginning May 1. 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. 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.

On March 22, 2010, jetBlue announced it would remain in the New York City area, in Long Island City, 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. 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.

Frequent flyers of jetBlue Airways can benefit from the airlineï¿½s loyalty program, TrueBlue.

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.
Chautauqua Airlines operated up to 12 Embraer 135 and 145 jets out of Milwaukee. Frontier began branding these flights as Frontier Express in the spring of 2011.

However, Frontier service to Rhinelander ended on January 3, 2013, and Chautauqua transferred the remaining aircraft to other partners.
