Like Ryanair, the low-cost airline founded by the Ryan family of Ireland, who also have invested in Allegiant, the airline seeks ancillary revenue to supplement ticket revenue.[13] These ancillary fees include those for checking luggage, carrying on luggage (other than a small personal item), buying food and drinks on board, obtaining advance seat assignments, and more.[33][40][41] Allegiant CEO Maurice Gallagher said in 2009, "We collect $110 from you at the end of your trip. If I tried to charge you $110 up front, you wouldn't pay it. But if I sell you a $75 ticket and you self-select the rest, you will."[42]
Allegiant Air (G4) is an American low-cost carrier that is headquartered in a suburb of Las Vegas. Founded in 1997, the airline does not use hubs, but has designated more than 10 focus cities. These include McCarran International Airport (LAS), Fort Lauderdale–Hollywood International Airport (FLL), Los Angeles International Airport (LAX) and Orlando Sanford International Airport (SFB). Although Allegiant flies into some major airports, many of its destinations are smaller cities or secondary airports that serve larger cities. In total, the airline serves about 105 domestic destinations in 41 states. The airline's fleet of 81 aircraft are each configured with a single Economy Class cabin.

A new marketing strategy has been partnerships with professional sports teams and venues. As the official airline of the New York Jets, JetBlue has specially painted the exterior of one of their Airbus A320s (N746JB) in the team's colors. Aircraft N605JB is based on the design of the Boston Red Sox road uniform and sports a grey fuselage with navy lettering. This aircraft was unveiled in February 2012, just in time for the opening of the Red Sox new spring training facility in Fort Myers, Florida named JetBlue Park at Fenway South. Additionally, JetBlue and MasterCard have pledged to refund select flight purchases made online at JetBlue.com using a MasterCard.[96] JetBlue has also partnered with various other sports teams and sporting venues in cities they serve.

The initial JetExpress partnership with Mesa ended in January 2004, when Horizon Air was selected to operate the routes. Horizon utilized slightly larger CRJ-700 regional jet aircraft on these routes. In August 2006, Frontier and Horizon ended their partnership.[64] While Frontier was generally pleased with Horizon's operation, the carrier decided that it needed to revisit the agreement and find a provider with additional regional jets to grow the operation. The last of the CRJ-700's was returned to the Horizon Air fleet on November 30, 2007.
