Like Ryanair, the low-cost airline founded by the Ryan family of Ireland, who also have invested in Allegiant, the airline seeks ancillary revenue to supplement ticket revenue. These ancillary fees include those for checking luggage, carrying on luggage (other than a small personal item), buying food and drinks on board, obtaining advance seat assignments, and more. Allegiant CEO Maurice Gallagher said in 2009, "We collect $110 from you at the end of your trip. If I tried to charge you $110 up front, you wouldn't pay it. But if I sell you a $75 ticket and you self-select the rest, you will."
In March 2011, Allegiant took over charter service to Wendover Airport for Peppermill Casinos, Inc. to shuttle customers to Peppermill's three casinos in West Wendover, Nevada; the Montego Bay Resort, the Rainbow Wendover and the Peppermill Wendover. Allegiant based one 150-seat, MD-80 series jet aircraft in Wendover and more than 20 employees, including maintenance, flight crews and stations personnel.
