The last of the CRJ-700's was returned to the Horizon Air fleet on November 30, 2007.
The worst! I'll never book with them again. If you have to make any changes to your itinerary, they connect you to a phone operator who can barely speak English. When i tried to add another room she would read a script before we would proceed, then before she could finish the price would increase and she had to restart, including the damn script she had to read. This happened 4 times before i told them to F-off and just cancelled my room altogether

In August 2012, the pilots voted to organize and joined the Teamsters. Allegiant's chairman and CEO, Maurice J. Gallagher Jr., has been critical of the unionization of airline employees, and has stated, "Unionization is one of those things that clogs the arteries and makes you less quick and not as nimble as you need to be on top of your game... In this industry and others that are heavily unionized, you ultimately end up with bankruptcy as the primary driver."
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.
