On October 25, 2007, the airline opened a fourth focus city and operations base at Phoenix-Mesa Gateway Airport in Mesa, Arizona, connecting 13 cities already served by Allegiant and one new city to the Phoenix metropolitan area. The airport announced a 10,000-square-foot (930 m2) expansion in August 2008, which increased the number of gates from two to four and allowed Allegiant to triple the number of flights from Phoenix. The expansion was funded by a loan from Allegiant which will be repaid by passenger fees.

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.

ABC interviewed a former Allegiant mechanic, who said "Dedicated steps were not being performed with maintenance manuals or even with general practices, before an aircraft is released." Many of these incidents had involved Allegiant's aging MD-80 aircraft, which as of November 2018 have been replaced by newer Airbus A320 family aircraft. 46 of the 86 aircraft have made emergency landings, all of which were on MD-80s. The average age of Allegiant's MD-80 fleet was 29 years compared to less than 13 years for its Airbus fleet.
Allegiant Air was founded in January 1997 by Mitch Allee (owner, CEO), Jim Patterson (president) and Dave Beadle (chief pilot), under the name WestJet Express.

The airline also has authority for charter service to Canada and Mexico.
