On April 10, 2008, Frontier filed for Chapter 11 bankruptcy in reaction to the intent of its credit card processor, First Data, to withhold significant proceeds from ticket sales.[better source needed] First Data decided that it would withhold 100% of the carrier's proceeds from ticket sales beginning May 1. According to Frontier's press release, "This change in practice would have represented a material change to our cash forecasts and business plan. Unchecked, it would have put severe restraints on Frontier's liquidity..." Its operation continued uninterrupted, though, as Chapter 11 bankruptcy protected the corporation's assets and allowed restructuring to ensure long-term viability. After months of losses, Frontier Airlines reported that they made their first profit during the month of November 2008, reporting US$2.9 million in net income for the month.
In October 2005, JetBlue's quarterly profit had plunged from US$8.1 million to $2.7 million largely due to rising fuel costs. Operational issues, fuel prices, and low fares, JetBlue's hallmark, were bringing its financial performance down. In addition, with higher costs related to the airline's numerous amenities, JetBlue was becoming less competitive.
Frontier Airlines is an American ultra low-cost carrier headquartered in Denver, Colorado. The eighth-largest commercial airline in the US, Frontier Airlines operates flights to over 100 destinations throughout the United States and six international destinations, and employs more than 3,000 air-travel professionals. The carrier is a subsidiary and operating brand of Indigo Partners, LLC, and maintains a hub at Denver International Airport with numerous focus cities across the US. In August 2018, Frontier began connecting passengers with Mexican low-cost carrier Volaris under a codeshare agreement.
In January 2010, the airline celebrated its one-millionth passenger to fly out of Phoenix-Mesa Gateway Airport. Allegiant's parent company also announced that it had purchased 18 new MD-80 aircraft from Scandinavian Airlines. In February 2010, Allegiant opened its ninth base at Grand Rapids' Gerald R. Ford International Airport in Michigan. The airline based two McDonnell Douglas MD-80 aircraft in Grand Rapids, but ended their airport's status in 2011. The airline continues to fly out of Grand Rapids in a reduced capacity.
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).
On October 31, 2017, the final 757 was retired from service, leaving Allegiant with only their A320 Family and MD-80 series fleets. In November 2018, the last MD-88s operated by Allegiant were retired, with Allegiant now operating an all-Airbus fleet. The move to the newer all-Airbus fleet has allowed Allegiant to benefit from lower fuel and maintenance costs, as well as operate in some airports which could not be served by the MD-80s.
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
Allegiant Air has been closely monitored by the FAA due to many emergency landings and aborted takeoffs. ABC interviewed a former Allegiant mechanic, who said "Dedicated steps were not being performed with maintenance manuals or even with general practices, before an aircraft is released." Many of these incidents had involved Allegiant's aging MD-80 aircraft, which as of November 2018 have been replaced by newer Airbus A320 family aircraft. 46 of the 86 aircraft have made emergency landings, all of which were on MD-80s. The average age of Allegiant's MD-80 fleet was 29 years compared to less than 13 years for its Airbus fleet.
In December 2015, the FAA issued a letter of correction due to an incident where an Allegiant aircraft attempted to fly to Hector International Airport in Fargo, ND in late July 2015, which was at the time within a temporary flight restriction due to a rehearsal by the Blue Angels flight team for an upcoming air show in Fargo respectively. The pilots flying the aircraft then declared a fuel emergency stating, "Yeah, listen, we're bingo (empty) fuel here in about probably three to four minutes and I got to come in and land." The pilots were scolded by the airport's tower who said, "Your company … should have been aware of this for a number of months," regarding the airspace restrictions which would have prevented flight to the airport. The pilots flying the aircraft were, at the time, the airline's vice president of flight operations and its director of flight safety.
