In 1997, Maverick Airways was operating code share service for Frontier with de Havilland Canada DHC-7 Dash 7 STOL capable turboprops between Denver (DEN) and two destinations in Colorado: Grand Junction (GJT) and Steamboat Springs (SBS).[66] However, the service was short lived as Maverick encountered financial challenges and then ceased all flights.
The company had charter contracts with Caesars Entertainment to ferry customers to Caesars casino properties through Reno-Tahoe International Airport, Laughlin/Bullhead International Airport and Tunica Municipal Airport.[48] These contracts ended in December 2012 when Caesars Entertainment signed a new contract with Republic Airways to provide the charter service to Caesars properties in Atlantic City, New Jersey, Tunica, Mississippi and Laughlin, Nevada.[49] 

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!
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.[22][23] 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.[24] In November 2011, Allegiant closed its Long Beach facility and consolidated all Los Angeles area flights at Los Angeles International (LAX).
In July 2017, Frontier announced 21 new cities and 84 new routes. These cities include Buffalo, Charleston, S.C., Pensacola, Jackson Hole, Palm Springs, San Jose, Reno, Little Rock, and Tulsa. Destinations that saw a significant bump-up in new service include Austin, Cincinnati, Long Island/Islip, N.Y., Miami, Orlando, Providence, San Antonio, and Tampa.[68]
On July 24, 2007, jetBlue reported that its second-quarter revenue increased to $730 million, compared to $612 in 2006. Second quarter net income grew to $21 million for the quarter, from $14 million the previous year. CEO David Barger said the airline will take delivery of three fewer planes this year and will sell three planes from their current fleet, "slowing capacity growth ... to strengthen our balance sheet and facilitate earnings growth", but will continue to add two to four new destinations each year.[25]
JetBlue Airways Corporation (NASDAQ: JBLU), stylized as jetBlue, is an American low-cost airline headquartered in New York City. A major air carrier and the sixth-largest airline in the United States. JetBlue is headquartered in the Long Island City neighborhood of the New York City borough of Queens, with its main base at John F. Kennedy International Airport. It also maintains corporate offices in Cottonwood Heights, Utah[6][7] and Orlando, Florida.
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.[83] 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. [84]
Allegiant also transports firefighters for the United States Forest Service as well as college basketball teams.[44] 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.[44] 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.[47]

As part of its plan to stay competitive in reaction to the entry of Southwest Airlines into Denver, the company underwent a reorganization early in 2006. On April 3, 2006, Frontier created Frontier Airlines Holdings (FRNT), a holding company incorporated in Delaware to take advantage of favorable tax laws in that state. The corporate headquarters did not leave Colorado.[21]
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.[citation needed]
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.[85] 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.[58]
Allegiant already flies into many major airports, including McCarran International (Las Vegas) and Fort Lauderdale-Hollywood International Airport. In June 2013, Allegiant deviated from this strategy with plans to compete with Southwest Airlines by offering direct flights between Las Vegas and Austin, a medium hub served by 10 carriers with non-stop routes to over 40 destinations. The airline also flies less frequently compared to the major airlines, operating routes two or three times per week. That requires fewer crews and allows less time-pressured aircraft maintenance.
In January 2008, Allegiant opened its sixth base at Washington's Bellingham International Airport. The airline bases two McDonnell Douglas MD-80 aircraft in Bellingham as part of the expansion.[19] Routes served exclusively from Bellingham include Las Vegas, Palm Springs, San Diego, San Francisco and Phoenix. Expansion in Bellingham has been largely driven by its proximity to Greater Vancouver, British Columbia.

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.[38] 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.[46] Republic Airways Holdings subsidiary Republic Airlines no longer flies Embraer 190 aircraft on behalf of Frontier, as of January 1, 2014.
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.[40]
