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.
In October 2013, Republic Airways Holdings entered into an agreement with private equity firm Indigo Partners to sell Frontier Airlines for approximately $145 million.

On September 9, 2014, Frontier introduced an updated livery, as part of a rebranding that saw the spokesanimals' roles increase. The new livery reintroduced a green "FRONTIER" typeface to the fuselage, featuring the stylized "F" designed by Saul Bass for the original Frontier in 1978. Each aircraft features the name of the animal featured on its tail near the nose of the aircraft for easier identification. Currently about twenty five aircraft in the Frontier fleet feature the new livery.
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.
