Allegiant aims primarily to serve leisure travelers, particularly those in colder northern climates, going to warm-weather tourist destinations such as Punta Gorda, Tampa Bay, Las Vegas, Orlando, Los Angeles and Phoenix. It also serves smaller destinations that see few direct flights by major carriers. Many of the airline's markets, such as Peoria, Illinois, are served only by commuter service requiring a connection at an airline hub. In October 2009, Allegiant had competition on just five of its 136 routes.
Today, it serves 77 cities on 176 routes. They cover destinations like Bellingham, Washington, Vancouver, British Columbia, Fort Lauderdale, Las Vegas, Nevada, Los Angeles, California, Myrtle Beach, Orlando, PhoenixMesa, Arizona, San Francisco Bay, Fort Myers and Tampa Bay or St. Petersburg-Clearwater. They have their operation bases at Bellingham International Airport, Fort Lauderdale-Hollywood International Airport, Las Vegas McCarran International Airport, Los Angeles International Airport, Oakland International Airport, Orlando-Sanford International Airport, PhoenixMesa Gateway Airport and St. Petersburg-Clearwater International Airport.
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. On February 20, 2007, jetBlue released an apologetic response to the events that had taken place less than a week before with the creation of their Customer Bill of Rights, which offers financial reciprocation if a customer's flight is delayed or cancelled.
At the checkin there was a male and I am assuming he was from Jamaica who was very impatient with us. We had even got our bags to the checkin before he was asking for our boarding passes and I’d cards. He stated that the boarding passes we had (which we printed the day before) would not work and through our boarding passes in the trash and after we presented our I’d cards proceeded to print out new boarding passes and our baggage claim tickets.
In March 2010, Allegiant purchased six used Boeing 757-200 jetliners as part of plans to begin flights to Hawaii, with deliveries from early 2010 to the fourth quarter of 2011. It gained the approval for type with the FAA in July 2011, and then worked with the FAA to obtain the appropriate ETOPS rating in order to be able to serve Hawaii. Allegiant no longer operates nonstop service to Honolulu from Las Vegas.
