In the March edition of Airways Magazine, it was announced that once jetBlue partnered with Yahoo! and with BlackBerry producer Research in Motion, that the airline would offer free, limited Wi-Fi capabilities on a single aircraft, N651JB, an Airbus A320-232 dubbed "BetaBlue". People access e-mail with a Wi-Fi capable Blackberry, or use Yahoo!'s e-mail and instant messaging with a Wi-Fi capable laptop, while in flight over the US. LiveTV in Melbourne Florida, created and operated the "BetaBlue" prototype. The "BetaBlue" system utilized the bandwidth and infrastructure of defunct Airfone.
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.

As Republic Airways Holdings was in the process of bidding to acquire Frontier in 2009, it was also in the process of acquiring Milwaukee-based Midwest Airlines. Through the fall and winter of 2009, Republic operated its two new acquisitions as separate brands. However, to improve efficiency by better matching aircraft capacity to route demand, Republic began to intermix the fleets of the two airlines, swapping a portion of its higher-capacity planes from Frontier with its smaller-capacity planes from Midwest and vice versa. However, the move caused some confusion amongst the public, as the two brands did not offer the same amenities and did not match the amenities mentioned on the airfare. As a result, in the Spring of 2010, Frontier and Midwest Airlines announced that their brands would merge, with Frontier being the surviving brand. This was a merger of brands only—no Midwest Airlines aircraft was ever operated by Frontier, as by this time, all Midwest Airlines flights were operated on its behalf by other Republic Airways Holdings subsidiaries.
