While its financial performance started showing signs of improvement, in February 2007, jetBlue faced a crisis, when a snowstorm hit the Northeast and Midwest, throwing the airline's operations into chaos. Because jetBlue followed the practice of never cancelling flights, it desisted from calling flights off, even when the ice storm hit and the airline was forced to keep several planes on the ground. Because of this, passengers were kept waiting at the airports for their flights to take off. In some cases, passengers who had already boarded their planes were kept waiting on the apron for several hours and were not allowed to disembark. However, after all this, the airline was eventually forced to cancel most of its flights because of prevailing weather conditions. The fiasco reportedly cost JetBlue $30 million.
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. 
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
According to Martin St. George, senior vice president of marketing and commercial strategy at jetBlue, the new "You Above All" campaign was created to get jetBlue back to their "DNA" and speak to the "core of who we are as a brand". This motto is meant to support their efforts to always put the customer first and "bring humanity back to air travel".
On July 1, 2010 Allegiant returned to Long Beach Airport (LGB) in Long Beach, California having previously served LGB with DC-9 jets with nonstop flights to Las Vegas (LAS) and Lake Tahoe (TVL) in 2000. The airline also intended to fly from Bellingham International Airport and Stockton several times a week; however, there is no service at present flown between these two cities although Allegiant continues to serve Stockton with flights to Las Vegas, Phoenix/Mesa and San Diego. In November 2011, Allegiant closed its Long Beach facility and consolidated all Los Angeles area flights at Los Angeles International (LAX).
In February 2011, Allegiant proposed to sell two types of tickets to passengers: advance tickets at a fixed higher rate and time-of-departure tickets that cost less but may have fees added based on the price of aviation fuel. In 2012, the U.S. Department of Transportation banned the practice as part of wider regulations that also require taxes and fees to be included in airfares. Allegiant, along with Spirit Airlines and Southwest Airlines, sued the DOT to overturn these new rules. The United States Court of Appeals for the District of Columbia Circuit ruled in favor of the DOT on 24 July 2012 and the US Supreme Court denied certiorari on 1 April 2013.
Worst airline ever!!! Had the worst experience and will never fly with them again. Although the flights are fairly cheap, it is more worth your time to spend a few extra dollars to fly with another airline. My flight was cancelled twice, then delayed another time. They gave me a 30 min notice before the cancellation and I had driven 5 hours to the airport... completely ridiculous and do not recommend.
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.
jetBlue previously had its headquarters at 80–02 Kew Gardens Road, and then in the Forest Hills Tower, both in Forest Hills, Queens, New York City, 6 miles (9.7 km) from the current office in Long Island City. In 2001 the airline had announced that it wanted to take 74,000 square feet (6,900 m2) of space in the Forest Hills Tower, and by December 2002 announced that it planned to increase its leased space.
In 2013, Allegiant acquired nine Airbus A320-200 aircraft from Spanish flag carrier Iberia. Seven of the A320s were delivered in 2013 and were used for growth into new markets, including destinations in Mexico and the Rocky Mountains, as well as airfields such as Charlottesville and Shenandoah Valley in Virginia and Trenton, New Jersey. On February 24, 2015, Allegiant announced the purchase of 2 additional A320s from Philippine Airlines which entered into service in 2015. Later in 2015, the airline announced a firm order for an Airbus A320 direct from Airbus, the first time it has purchased new aircraft from the supplier.
I just had horrendous experience and customer service! I booked a round trip flight for my son from Stockholm to Zurich via Amsterdam. It was 185 USD. Travelocity emailed us on the day of the flight that the flight from Amsterdam to Zurich and all return flights were cancelled. My son ended up booking a new flight from Stockholm to Zurich that costed him about 500 USD. I reached out Travelocity customer service via Facebook. The rep admitted that email was an error but ensured me that return flight was still good. However, my son was charged 285 USD penalty on the return flight for missing the first leg. In the end, he ended up paying 800 USD out of his pocket. Short flight cost us a total of 1000 USD! The reps via Facebook said they were sorry but they would not do anything to compensate/reimburse me or be accountable for their mistakes. I will NEVER use Travelocity again for sure!!
Allegiant also transports firefighters for the United States Forest Service as well as college basketball teams. Allegiant had a contract to supply charter flights from Miami to four cities in Cuba beginning June 2009. One aircraft was committed to the contract. The contract was for fixed-fee flying, meaning all the airline was required to do was provide the dry aircraft and the flight crew. The contractor was responsible for all other costs including fuel. However, Allegiant ended this service in August 2009.
