In October 2013, Republic Airways Holdings entered into an agreement with private equity firm Indigo Partners to sell Frontier Airlines for approximately $145 million. According to Indigo, the transaction would further Frontier's evolution into an ultra-low-cost carrier. In December 2013, Indigo Partners LLC, through an affiliate, completed the purchase of Frontier Airlines from Republic Airways Holdings. The airline's headquarters will remain in Denver. Republic Airways Holdings subsidiary Republic Airlines no longer flies Embraer 190 aircraft on behalf of Frontier, as of January 1, 2014.
The flight personnel and cabin crew where not friendly at all and continuously knocked my shoulders (which where wider than the sear backs) every time they came by and hit my right leg which I had placed on the outside of the seat in front of me as I had a brace on that leg and did say excuse me or I’m sorry the whole time that they hit my leg or my shoulder. By the way and I didn’t tell them but I have undergone reverse shoulder surgery on both of my shoulders/arms and I really don’t expect to get hit every time they pass me
The airline tends to offer lower fares, which requires strict cost control. Part of the airline's lower cost structure included operation of McDonnell Douglas MD-80 jets, which the airline can purchase and refurbish for as little as $4 million. While the aircraft are less fuel-efficient than newer planes, Allegiant was able to purchase used MD-80s outright for one-tenth the cost of a new Boeing 737 although Allegiant has subsequently purchased used Boeing 757-200s, Airbus A319s and Airbus A320s. (The 757s were acquired for its Hawaii service while the Airbus jets were beginning to replace MD-80 aircraft). As of November 2018, however, Allegiant no longer operates any MD-80 aircraft, relying instead on an all-Airbus fleet. Given the low cost of ownership, Allegiant is able to operate its aircraft less (seven flight hours per day on average versus 13 hours per day at JetBlue Airways), which helps keep labor costs lower. Overall, Allegiant operates with 35 full-time workers per plane compared to more than 50 at other carriers. Allegiant schedules their crew members so that they always return to their domicile at the end of the day, thus avoiding the need for hotel rooms which can be a costly expense for airlines.
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.
