Tolong jelaskan mengenai Ancillary revenue dari Allegiant Air

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."

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. Commissions on hotel and rental car packages are up to one-third of the airline's revenue.

In 2009, ancillary revenues were $33.35 per passenger.
