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.
In an effort to focus on regional contract flights for major carriers, Republic Airways Holdings announced in January 2012 its intention to sell or spin off Frontier. On January 26, 2012, Republic Airways Holdings appointed former US Airways and Gate Gourmet CEO David Siegel as President and CEO of Frontier Airlines. Republic also added new senior officers for Frontier's finance and commercial team, among other changes in the executive leadership team. Siegel and other Frontier executives moved to Denver where Frontier is headquartered in order to facilitate management of all aspects of Frontier during its separation process from Republic and continue its transformation into an ultra-low-cost carrier.
In May 2017, Allegiant Air took delivery of its first brand-new A320. Allegiant took delivery of ten new A320s in 2017 and is scheduled to accept two in 2018. All new aircraft will be painted in Allegiant's new livery at the time it is delivered. Older Airbus aircraft will be repainted during their C-checks. The new Airbus aircraft will have fuel-efficient sharklets. The new A320s seat 186 passengers, an increase of the 177 seats that are found in the rest of the Allegiant A320 fleet. To fit the additional nine seats, Allegiant opted for the Airbus Space-Flex V2 Lavatory.

On October 13, 2009, the airline unveiled a modification to its livery in commemoration of the upcoming 10th anniversary of the airline in February 2010. Besides a new tail design, the revised livery includes larger "billboard" titles extending down over the passenger windows at the front of the aircraft. The logo word 'jetBlue' will no longer be silver and blue but now a dark, navy blue.
On March 22, 2010, jetBlue announced it would remain in the New York City area, in Long Island City, because of the airline's historical links to the city, the cost of staff relocations, the airline's desire to retain access to financial markets, and because Aer Lingus and Lufthansa, jetBlue's marketing partners, fly into JFK Airport. jetBlue planned to combine its Forest Hills and Darien, Connecticut offices, together about 1,000 employees, into about 200,000 square feet (19,000 m2) in the Brewster Building by mid-2012.
I fly a lot. I've never seen any flight that cannot be refunded within a 24 hour period. When shopping around, I will sometimes but 2 or 3 tickets before settling on one. Now I have. Travelocity sold me one. I called the airline and they were super helpful, as much as they could be. But the representative said she'd never seen a ticket like this either. She had no way of refunding it. And I don't necessarily have an issue with the restriction itself, I have an issue with it not being clear during the purchase process. And I further take issue with the customer service person telling me I'm a liar. Just crazy.
On March 19, 2008, jetBlue added Orlando, Florida as a gateway focus city to international destinations in the Caribbean, Mexico, and South America. New international routes from Orlando International Airport include Cancún, Mexico, Bridgetown, Barbados, Bogotá, Colombia, Nassau, Bahamas, San José, Costa Rica, and Santo Domingo, Dominican Republic. In conjunction with the addition of new routes the airline will continue significant expansion of operations at Orlando International Airport including a planned 292-room lodge that will house trainees attending the existing "JetBlue University" training facility (opened in 2015).
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.
They lost my hotel reservation the 1st time a couple of years ago. I received a credit of $100 that I was told wouldn't expire. Tried to use it for my flight a couple of days ago and it expired. I booked my flight and paid extra to be able to choose my seat. When logging into United to choose my seat, the only option other than where they put me (last row of the plane by bathrooms and in a middle seat) was to pay for a more premium seat, paying an extra $50. Called Travelocity in hopes that someone would help make it right, but there was nothing they could do. Customer service at it's finest. I thought I would give them another chance but this was the last. I've never EVER had a problem with Priceline and will continue to use them. Just booked my car and hotel with them when Travelocity could have rectified the situation and got that business as well.
