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). However, the service was short lived as Maverick encountered financial challenges and then ceased all flights.
Also in 2010, JetBlue entered into interline booking agreements with South African Airways and American Airlines to facilitate luggage transfers between airlines for passengers with connecting flights on a different carrier. The agreement with American included JetBlue's 18 destinations not served by American and American's 12 international flights out of New York–JFK and Boston Logan. In addition, American gave JetBlue 8 round trips slots out of Washington National in D.C. and 2 out of Westchester, New York. In return, JetBlue gave American 6 round trips out of New York–JFK. The agreement with American Airlines has since ended according to JetBlue's website.
A November 2016 analysis by the Tampa Bay Times noted that Allegiant's planes were four times more likely to have in-flight failures than other major US airlines. A 60 Minutes report by CBS News in 2018 continued to investigate the issues first raised by the Tampa Bay Times. Public records cited in the investigation found that the airline had more than 100 serious mechanical incidents between January 1, 2016 and October 31, 2017, including "mid-air engine failures, smoke and fumes in the cabin, rapid descents, flight control malfunctions, hydraulic leaks and aborted takeoffs." Other public records further revealed that Allegiant aircraft, on average, were nearly three and a half times more likely to have mid-air breakdowns than American, United, Delta, JetBlue and Spirit.
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.
