Animal concepts used in the livery extend into Frontier's marketing as well. Each animal has a specific name.[87] Animal aircraft used in their radio and television commercials include Jack the rabbit, Grizwald the bear, Foxy the fox (for whom Jack has a crush), Flip the dolphin (who always gets stuck going to Chicago rather than the warmer climates the others are going to), Larry the lynx, Hector the sea otter, and Sal the cougar. New additions are Penguins Jim, Joe, Jay, and Gary, a barbershop-style quartet, singing the praises of EarlyReturns to an audience of Frontier's well-known characters from the "a whole different animal" campaign, Hector the otter, advertising Frontier's expanding service to Mexico, and Polly the Parrot, who won the new animal audition in 2012.

In 1997, Maverick Airways was operating code share service for Frontier with de Havilland Canada DHC-7 Dash 7 STOL capable turboprops between Denver (DEN) and two destinations in Colorado: Grand Junction (GJT) and Steamboat Springs (SBS).[66] However, the service was short lived as Maverick encountered financial challenges and then ceased all flights.
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]

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]
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.
In February 2002, the airline launched its first regional product, Frontier JetExpress, initially operated by Mesa Airlines using CRJ-200 regional jets. Similar to "express" operations of other carriers, Frontier JetExpress was targeted for markets to and from Denver that do not generate traffic sufficient to support Frontier's smallest mainline jet, the Airbus A318, but could still offer lucrative business with a smaller jet.
Various consumer rights organizations and activists called for the creation of a government mandated “Bill of Rights” to protect air travelers from future experiences similar to the one previously described. On February 20, 2007, jetBlue released an apologetic response to the events that had taken place less than a week before with the creation of their Customer Bill of Rights, which offers financial reciprocation if a customer's flight is delayed or cancelled.[99]
