In July 2012, the U.S. Department of Transportation fined Travelocity $180,000 after discovering that Travelocity's “flexible dates tool” did not always include fuel surcharges that were part of many international airfares in violation of the Department's rules requiring all carrier-imposed surcharges and fees to be included in every advertised fare. In addition, the DOT found that the customer was informed only on the final page before purchasing the ticket that some itineraries required a paper ticket with a minimum additional delivery fee of $29.95.[29]
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]
Frontier was ranked in an airline quality rating report by Embry-Riddle Aeronautical University and Wichita State University in 2015 as one of the five worst airlines in the United States, especially due to its rate of customer complaints and bumped passengers.[88][51][89] The airline also had relatively poor on-time performance, and the waiting time for help when calling the airline on the phone was reported to have risen to two hours or more.[90]

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.[15] 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.[16]
In September 2009, JetBlue made changes to its TrueBlue program.[132] In the new program, members receive three points for every dollar spent toward a flight, excluding taxes and fees, plus an additional three points for every dollar spent on a flight if booked online directly on the JetBlue.com website. Additional points are awarded if the member uses the Barclay's issued JetBlue Mastercard credit card to purchase the flight. The price of flights in points depend on the fare of the flight in U.S. dollars. The new program launched on November 9, 2009.[133][134]

In February 2012, Frontier Airlines cut five nonstop routes from Milwaukee. This move "reduced Frontier's daily departing flights out of Mitchell International from 32 to 18," or 56%. Frontier announced further layoffs in conjunction with this route change: up to 446 Milwaukee-area employees were affected by the job cuts that occurred between April 15 and April 30, 2012.[37] 

Animal concepts used in the livery extend into Frontier's marketing as well. Each animal has a specific name.[87] Animal aircraft used in their radio and television commercials include Jack the rabbit, Grizwald the bear, Foxy the fox (for whom Jack has a crush), Flip the dolphin (who always gets stuck going to Chicago rather than the warmer climates the others are going to), Larry the lynx, Hector the sea otter, and Sal the cougar. New additions are Penguins Jim, Joe, Jay, and Gary, a barbershop-style quartet, singing the praises of EarlyReturns to an audience of Frontier's well-known characters from the "a whole different animal" campaign, Hector the otter, advertising Frontier's expanding service to Mexico, and Polly the Parrot, who won the new animal audition in 2012.
Frequent flyers of jetBlue Airways can benefit from the airline�s loyalty program, TrueBlue. The carrier takes a high-tech approach to their "flight gratitude program," skipping membership cards and paper mailings in favor of online operations. Points earned through jetBlue or its partners do not expire, as long as the member flies with the airline at least once per year. Points are earned for flights booked, with members accumulating three points for every dollar spent on a jetBlue service. The carrier awards double points if members book online.
On March 22, 2010, jetBlue announced it would remain in the New York City area, in Long Island City,[88] because of the airline's historical links to the city, the cost of staff relocations, the airline's desire to retain access to financial markets, and because Aer Lingus and Lufthansa, jetBlue's marketing partners, fly into JFK Airport.[89] jetBlue planned to combine its Forest Hills and Darien, Connecticut offices, together about 1,000 employees, into about 200,000 square feet (19,000 m2) in the Brewster Building by mid-2012.[90]
On June 22, 2009, Frontier Airlines announced that pending bankruptcy court approval, Republic Airways Holdings, the Indianapolis-based parent company of Republic Airlines, would acquire all assets of Frontier Airlines for the amount of $108 million. Thus, Frontier Airlines would become a wholly owned subsidiary of Republic.[26] However, 5 weeks later on July 30, Dallas-based Southwest Airlines announced that it would be making a competing bid of $113.6 million for Frontier with intentions to also operate Frontier as a wholly owned subsidiary, but that it would gradually fold Frontier resources into current Southwest operating assets.[citation needed]
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.

March 27, 2012: Flight 191 en route from New York City, to Las Vegas performed an emergency landing at Rick Husband Amarillo International Airport after the captain, Clayton Osbon, was locked out of the cockpit and subdued by passengers after he started acting erratically and ranting about terrorist. It is believed that Osbon suffered from an unspecified mental breakdown, and was treated by Northwest Texas Healthcare System. There were no fatalities.[148][149][150]
jetBlue expanded service to the Caribbean, including to St. Maarten and Puerto Plata commencing January 10, 2008. With these additional destinations, jetBlue serves a total of twelve Caribbean/Atlantic destinations including Aruba; Barbados; Bermuda; Cancún; Nassau; Aguadilla; Ponce; San Juan, Puerto Rico; Santiago; and Santo Domingo, Dominican Republic.[citation needed]

While its financial performance started showing signs of improvement, in February 2007, jetBlue faced a crisis, when a snowstorm hit the Northeast and Midwest, throwing the airline's operations into chaos. Because jetBlue followed the practice of never cancelling flights, it desisted from calling flights off, even when the ice storm hit and the airline was forced to keep several planes on the ground. Because of this, passengers were kept waiting at the airports for their flights to take off. In some cases, passengers who had already boarded their planes were kept waiting on the apron for several hours and were not allowed to disembark. However, after all this, the airline was eventually forced to cancel most of its flights because of prevailing weather conditions.[17] The fiasco reportedly cost JetBlue $30 million.[18]
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 late 2009 Republic began to consolidate administrative positions and moved 140 jobs from the Frontier Airlines Denver headquarters to Indianapolis, Indiana.[29] Shortly after that, in January 2010, Republic Airways announced that it would move all of its executives to Indianapolis.[30] In February the Denver Business Journal stated that the headquarters would be moved "soon".[31] Despite this, according to the Denver Business Journal, Frontier Airlines will still maintain a local headquarters in Denver to house Training, Marketing, Customer Reservations, and Scheduling & Planning teams after extending its lease on the building through 2020.[citation needed]
In 2008, jetBlue partnered with Irish flagship carrier Aer Lingus to allow passengers to switch between airlines on a single ticket for flights with connections in New York–JFK or Boston Logan. Unlike traditional codeshare agreements, the companies cannot sell seats on each other's flights, so customers initiate the purchase on one airline's website and then are transferred to the other site to complete the transaction.[105][106]
Founded in 1997 as WestJet Express, the company was renamed as Allegiant Air and started operations under the new name in 1998. From there on, company went on to become one of the most favorite low-cost airlines of America with their unmatched reliability, customer care and best in-class deals. Owned by Allegiant Travel Co. Allegiant Air have their headquarters in Enterprise, Nevada near Las Vegas. Today it has more than 1300 employees and over a billion USD capitalizations.
In October 2013, jetBlue introduced Mint, a premium cabin service on transcontinental and select Caribbean flights. The service began in 2014, using the Airbus A321-231 aircraft ordered by jetBlue. These planes are outfitted with winglets, as well as with "lie flat" seats, and moveable partitions that can create small suites on the airplane.[56] Called "Mint" by jetBlue, these planes are configured with 16 business-class seats and 143 economy seats, instead of an all-economy configuration of 190 seats.[57]
The TWA Hotel is the TWA Flight Center structure currently being rebuilt as 505-room hotel, preserving the Eero Saarinen headhouse while replacing the structures on either side of the headhouse. Situated in front of JetBlue's JFK terminal, JetBlue has stated that it estimates the ownership of the hotel would be between 5–10% of the final total investment.[138] The hotel will be an effective replacement for the Ramada Plaza JFK Hotel on the north end of the airport grounds in Building 144, which closed in 2009.
The American airline serves more than 60 destinations in its multinational network, with locations in North, South and Central America. Canadian travelers are able to board jetBlue flights by connecting at any of its major hubs in the United States. Transitions are easy for customers who book flights with the airline's partners, which include Aer Lingus, Lufthansa, South African Airways, Cape Air and Emirates Airlines.

JetBlue Technology Ventures (JTV) [137] is a wholly owned subsidiary of JetBlue that was established in February 2016.[138] JTV is the venture capital arm of JetBlue that invests in and partners with early-stage startups in the travel, hospitality, and transportation space. Its mission is to improve the end-to-end experience of travelers everywhere. As of November 2018, JTV has invested in 21 startups, including hybrid planes,[139] machine learning algorithms,[140] and ground transportation.[141] Investments range in size from $250,000 to $1 million.[142]
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]
