Nevada-based Allegiant (G4) is a low-cost carrier that flies all Economy Class aircraft to about 100 destinations in 40 US states. On many routes, it only operates a couple times a week, and it typically flies to smaller, regional airports. However, Allegiant's focus cities include a mix of smaller and larger airports, including Bellingham International Airport (BLI), Fort Lauderdale–Hollywood International Airport (FLL), Los Angeles International Airport (LAX), Las Vegas's McCarran International Airport (LAS) and Phoenix–Mesa Gateway Airport (AZA).
Various consumer rights organizations and activists called for the creation of a government mandated “Bill of Rights” to protect air travelers from future experiences similar to the one previously described.

In September 2009, JetBlue made changes to its TrueBlue program. 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.
