Buyer beware! Do not use this service! I booked a trip for my son and then needed to change the reservation the next day. The customer service person said to cancel the first trip and "re book the whole reservation again (my son needed to stay 2 extra days). A partial refund came in 2 days later for the cost of the hotel. The refund was short $500.00 for the airfare. I called after about 6 days and was told it was being processed and would take up to 7 days. I called 5 days later (day 11) and was told it was processed and the hold up was on the part of my bank. I called the bank who had no record of this at all. They are now disputing the charges with Travelocity. It's been a time consuming and aggravating nightmare. Be aware and careful before you use Travelocity. In looking at their reviews this is not an isolated instance. They seem to have very poor business practices throughout!
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 airport director in Worcester, Massachusetts, felt that Allegiant reneged on a commitment to serve the airport for five years given the use of federal grants to assist its startup. However, the airline responded that the market was immediately unprofitable and starting service there was a poor decision; flights were reported to be 80% full. Allegiant's flights average 90% full.
As of April 2019, jetBlue Airways flies to 102 destinations in North, Central, and South America; including destinations in Aruba, The Bahamas, Barbados, Bermuda, Cayman Islands, Colombia, Costa Rica, Cuba, the Dominican Republic, Ecuador, Grenada, Haiti, Jamaica, Mexico, Peru, Puerto Rico, Saint Maarten, Saint Lucia, Trinidad and Tobago, Turks and Caicos Islands, and the United States.
In August 2017, Allegiant announced a new base would be established at the Indianapolis International Airport. The base began operations in early 2018. In February 2018, Allegiant also announced a new base would be established at the Destin–Fort Walton Beach Airport. In June 2018, Allegiant added another base at McGhee Tyson Airport in Knoxville, Tennessee. In January 2019, Allegiant announced they would be adding another base at Gerald R. Ford International Airport in Grand Rapids, Michigan.
During the last few days of June and the first few days of July 2015, jetBlue began charging for bags in certain booking classes, leaving Southwest Airlines the only major U.S. carrier to not charge for bags. For the classes in which bag check fees are charged (generally the lowest class of fares offered; jetBlue offers 3 classes of fares), the cost is $20 for the first bag and $35 for the second, which is the lowest in the United States besides Frontier Airlines with similar prices.
In summer 2015, a rash of midair breakdowns drew federal scrutiny. "Before the night was finished on June 25, 2015, five Allegiant flights had been interrupted in four hours, all because different planes had failed in midair," reported the Tampa Bay Times. Since October 2015, the Federal Aviation Administration has kept Allegiant under close supervision. In July 2015, Allegiant Air announced bases would be established at the Asheville Regional Airport and Cincinnati/Northern Kentucky International Airport, becoming the first base at a non-vacation destination.

In April 2010, Allegiant purchased six Boeing 757-200 aircraft from Thomson Airways for flights to Hawaii with the delivery of the first two in the following months. In September 2011, Allegiant Air introduced the 757 into service from their main hub in Las Vegas. Allegiant later began using the ETOPS configured 757s for service to Hawaii. Fresno and Las Vegas were the inaugural destinations with nonstop service to Honolulu, Hawaii. Nonstop service to Honolulu was then added from Bellingham, Boise, Eugene, Phoenix (via Mesa Gateway Airport), Santa Maria, Spokane and Stockton. Nonstop service to Hawaii was also planned from Monterey, CA but was not actually operated. Allegiant then began to reduce its Hawaii service after determining that the extensive and costly maintenance check - which happens about every six years and costs upwards of $1 million - would not be efficient on the aircraft they flew to Hawaii.
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.
