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. 

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.[23][better source needed] First Data decided that it would withhold 100% of the carrier's proceeds from ticket sales beginning May 1.[24] 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.[citation needed] 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.[25]
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.

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!!

Frontier Miles is the frequent-flyer program for Frontier Airlines, replacing the EarlyReturns program, which existed from 2003 to 2018.[70] Frontier Miles can be earned by flying Frontier Airlines, using the Frontier Airlines World MasterCard, or by spending at partner hotels, car rental chains, cruises, and merchants.[71] Frontier Miles can be redeemed for flights, magazine subscriptions, and car rentals.[72] Since February 2019, hotel stays are also part of the redemption options.[73]
As jetBlue gained market share, they found a unique positioning where they competed with other low-cost carriers (e.g. Southwest, and Frontier), as well as major carriers (e.g. American, United, and Delta). Amenities such as their live in-flight television, free and unlimited snack offerings, comfortable legroom, and unique promotions fostered an image of impeccable customer service that rivaled the major airlines, while competitive low fares made them a threat to low-cost no-frills carriers as well.[94]
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.
Allegiant also earns commissions by offering hotel rooms, car rentals and admission to tourist attractions on its website. It sells package vacations under the brand name Allegiant Vacations. The company has arrangements with 34 hotels in Las Vegas and 21 in the Orlando and Daytona Beach, Florida, areas. In 2008, the airline sold 400,000 hotel room nights.[42] Commissions on hotel and rental car packages are up to one-third of the airline's revenue.[40][42]
jetBlue's founders had set out to call the airline "Taxi" and therefore have a yellow livery to associate the airline with New York. The idea was dropped, however, for several reasons: the negative connotation behind New York City taxis; the ambiguity of the word taxi with regard to air traffic control; and threats from investor JP Morgan to pull its share ($20 million of the total $128 million) of the airline's initial funding unless the name was changed.[13]
On October 22, 2008, jetBlue opened its new primary hub at John F. Kennedy International Airport (JFK), Terminal 5, or simply T5. The mostly new terminal, costing approximately $800 million,[41] partially encircles the historic TWA Flight Center, the former Trans World Airlines terminal designed by Eero Saarinen, which remains closed. According to the plan, passengers will eventually be able to check in for flights in the landmark building, then transfer to the new structure via the original passenger departing-arrival tubes from Saarinen's original terminal and its 1969 addition by Roche-Dinkeloo.[42]

In February 2002, the airline launched its first regional product, Frontier JetExpress, initially operated by Mesa Airlines using CRJ-200 regional jets. Similar to "express" operations of other carriers, Frontier JetExpress was targeted for markets to and from Denver that do not generate traffic sufficient to support Frontier's smallest mainline jet, the Airbus A318, but could still offer lucrative business with a smaller jet. 

In July 2016, jetBlue announced commercial flights from the United States to Cuba will commence in late August.[64][65] On August 31, 2016, JetBlue Flight 387 from Fort Lauderdale–Hollywood International Airport to Abel Santamaría Airport, in Santa Clara, became the first scheduled commercial flight between the United States and Cuba in 55 years.[66] Only charter flights were allowed under previous rules, which required that passengers had to arrive more than 4 hours before the scheduled departure and often endure long lines for documentation checks, late flight arrivals, and pay high baggage fees.[67]
A November 2016 analysis by the Tampa Bay Times noted that Allegiant's planes were four times more likely to have in-flight failures than other major US airlines.[64] A 60 Minutes report by CBS News in 2018 continued to investigate the issues first raised by the Tampa Bay Times.[65] Public records cited in the investigation found that the airline had more than 100 serious mechanical incidents between January 1, 2016 and October 31, 2017, including "mid-air engine failures, smoke and fumes in the cabin, rapid descents, flight control malfunctions, hydraulic leaks and aborted takeoffs."[65] Other public records further revealed that Allegiant aircraft, on average, were nearly three and a half times more likely to have mid-air breakdowns than American, United, Delta, JetBlue and Spirit.[65]
