In late 2009 Republic began to consolidate administrative positions and moved 140 jobs from the Frontier Airlines Denver headquarters to Indianapolis, Indiana. Shortly after that, in January 2010, Republic Airways announced that it would move all of its executives to Indianapolis. In February the Denver Business Journal stated that the headquarters would be moved "soon". Despite this, according to the Denver Business Journal, Frontier Airlines will still maintain a local headquarters in Denver to house Training, Marketing, Customer Reservations, and Scheduling & Planning teams after extending its lease on the building through 2020.
jetBlue experienced its first-ever quarterly loss during the fourth quarter of 2005 when the airline lost $42.4 million, enough to make them unprofitable for the entire year of 2005. The loss was the airline's first since going public in 2002. JetBlue also reported a loss in the first quarter of 2006. In addition to that, jetBlue forecasted a loss for 2006, citing high fuel prices, operating inefficiency, and fleet costs. During the first quarter report, CEO David Neeleman, President Dave Barger, and then-CFO John Owen released JetBlue's "Return to Profitability" ("RTP") plan, stating in detail how they would curtail costs and improve revenue to regain profitability. The plan called for $50 million in annual cost cuts and a push to boost revenue by $30 million. jetBlue Airways moved out of the red during the second quarter of 2006, beating Wall Street expectations by announcing a net profit of $14 million. That result was flat when compared to jetBlue's results from the same quarter a year before ($13 million), but it was double Wall Street forecasts of a $7 million profit, Reuters reports. The carrier said cost-cutting and stronger revenue helped it offset higher jet fuel costs. In October 2006, jetBlue announced a net loss of $500,000 for Quarter 3, and a plan to regain that loss by deferring some of their E190 deliveries and by selling 5 of their A320s.
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.
Frontier took delivery of its first Airbus aircraft (an A319) in 2001 and simultaneously launched with it DirecTV in-flight television along with a new company livery. Frontier Airlines was the launch customer of the Airbus A318 in 2003. In mid-April 2005, Frontier officially became an all-Airbus fleet, retiring its last Boeing 737.
We arrived at the airport at 5:15 for our 7:15 flight. After two delays we received a text message from the company that the flight had been canceled. 35 minutes later an employee finally came out to announce the cancellation. As we started asking questions like “will we get our money back” or “do you have any more flights going out we can get on” each time a piece of paper was picked up and shaken in our faces and were told to read the paper just like everyone else. Worst service ever!!!!!! We were all states away from home with no where to go and no help from frontier. And our refund could be expected within two weeks. All I could think of is how I hoped everyone there could find funds to purchase another ticket to where they were going. Because last minute tickets are crazy expensive. I will never fly frontier again!!!! They gave me a $100 voucher off my next flight with them but I’ll never use it!!!
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. 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.
