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.
Frontier Airlines (F9) is a Denver-based low-cost carrier. The carrier flies to about 65 destinations in the United States, Costa Rica, the Dominican Republic, Jamaica and Mexico. Its fleet of planes each feature a single Economy Class cabin. However, passengers can upgrade to Select Seating, which is located toward the front of the plane, or Stretch Seating, which features more legroom. Frontier's hub is based at Denver International Airport (DEN). An additional eight airports have been designated as focus cities. The airline has a codeshare agreement with Great Lakes Airlines.
In 2014, Frontier announced it would be transitioning into an ultra-low cost carrier. Frontier will also cut several flights and jobs at their Denver hub and transition them to different markets. On January 16, 2015 Frontier announced that it will close both its Denver and Milwaukee call centers, laying off 1,300 employees and outsourcing the jobs to call center company, Sitel, which operates a large call center for Frontier in Las Cruces, New Mexico. As part of its transition to an ultra-low-cost airline, Frontier Airlines joined Spirit and Allegiant in June 2015 in removing its toll-free telephone number for customer service.
In February 2015, Frontier announced that they will begin service to several destinations from Atlanta adding the airport as a focus city. In July, Frontier also began decreasing service from Washington Dulles International Airport removing the airport as a focus city. In early 2016 Frontier announced major route expansion from airports nationwide including Atlanta, Chicago, Cincinnati, Cleveland, Orlando, and Philadelphia. In June 2016, Frontier re-established service to Port Columbus International Airport. In May 2017, the airline announced opening a new crew base in Las Vegas in the fall 2017 to improve operational reliability and potentially create new jobs in Las Vegas. In December 2017, Frontier began service to Buffalo, New York, with service to Denver, Colorado, and Florida, including Miami, Fort Myers, Orlando, and Tampa.
In July 2013, Frontier started service from New Castle Airport near Wilmington, Delaware to five destinations, which Frontier markets as Wilmington/Philadelphia. Again, this airport had no commercial service prior to Frontier's entry. New Castle Airport lies roughly 30 miles southwest of Philadelphia International Airport and 75 miles northeast of Baltimore–Washington International Airport.
After booking a excursion in St Maarten that never happened as the companies website and phone number were taken down so no final arrangements could be made. Called travelocity twice and still can not seem to get it through their heads about the service not happening. They tried contacting the company....no luck then they asked me for the contact information I had.....are you kidding me it is your contracted service (IDIOTS)....anyway none of my contact info worked for the company why badger me.....just give me my refund. I will post followups as they happen
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.
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
I had to make some last minute travel changes and needed to SUBTRACT 2 days from my 9 day car rental reservation. The customer service agent refused to get me to her supervisor after I asked her multiple times because she was trying to charge me more money to take two days off my rental!!! Finally she told me she found something for $205 (my original rental was $268). I said, now that makes more sense. It's the same car? She said yes, I said lets make the change. Then AFTER she completed the transaction she told me that she hadn't added any of the taxes and fees so my new total is $277! Ten dollars more for two days less!! I told her that she mislead me and that she should be ashamed of herself and the company should be ashamed of itself. Obviously it doesn't care about the slew of ONE STAR reviews it has because it's not making any changes to help their customers!
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. 
What makes them so good is the fact that they genuinely strive to give their guests all kinds of luxuries and an experience of leisure travel at unbelievably affordable prices. It has all the horse power that one can imagine a complete airline to have in the form of low fares, all-jet non-stop service to almost anywhere in America, Mexico and Canada and world-class travel partners. Ever since it was certified by the U.S. Department of Transportation (DOT) as a “Scheduled Air Carrier” it has been operating as scheduled and chartered airlines much to the delight of its guests all over America.
We arrived at the airport at 5:15 for our 7:15 flight. After two delays we received a text message from the company that the flight had been canceled. 35 minutes later an employee finally came out to announce the cancellation. As we started asking questions like “will we get our money back” or “do you have any more flights going out we can get on” each time a piece of paper was picked up and shaken in our faces and were told to read the paper just like everyone else. Worst service ever!!!!!! We were all states away from home with no where to go and no help from frontier. And our refund could be expected within two weeks. All I could think of is how I hoped everyone there could find funds to purchase another ticket to where they were going. Because last minute tickets are crazy expensive. I will never fly frontier again!!!! They gave me a $100 voucher off my next flight with them but I’ll never use it!!!
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.
