The Las Vegas-based airline charges extra to book flights online, or to use a credit card. Selecting a seat in advance costs $5 to $75 each way, depending on the length of a flight. Even a bottle of water costs $2.
Like some other budget airlines, Allegiant advertises extremely low base fares and then tacks on numerous fees. A roundtrip ticket with Allegiant costs $195, on average. But passengers pay an additional $83 in fees — or 30 percent of the total cost of flying.
To book a trip by phone, Allegiant charges $50 for each roundtrip ticket. To book online costs $20 for each roundtrip ticket. The only way to avoid the fees is to purchase tickets at the airport, something fewer than 3 percent of its customers did last year.
But whether you book by phone, Internet or in person, paying with a credit card costs an extra $8.
Placing a suitcase in an overhead bin is $10 to $25. Boarding passes signify who has paid the fee. If passengers show up at the airport with a large carry-on bag and haven't prepaid the fee, the airline penalizes them an additional $25 to $50, depending on the route.
Flying Allegiant isn't glamorous. While other airlines tout new aircraft with Wi-Fi and TVs in every seat, Allegiant buys old planes to avoid hefty aircraft loans. And to pack in as many passengers as possible, its seats don't recline. But for small-town Americans with limited flight options, these inconveniences are worth it for a few days of sunshine.
Allegiant is ruthless about keeping its costs down. Its employees are some of the lowest paid in the industry, in some cases making $20 an hour less than colleagues at other airlines. It pays cash for airplanes nearly twice as old as everyone else. It only sells directly to vacationers, refusing to pay Expedia, Orbitz or other sites to list its flights.
And if you have a question, it will cost you: the airline doesn't have a toll-free number.
The bigger problem is if a mechanical issue forces a plane to be grounded. Given its limited schedule and packed planes, there usually isn't another flight to book passengers on. Instead, they are left waiting six hours while a new plane is flown in.
Sometimes flights are postponed to the next day. In one extreme situation in March, more than 1,700 passengers flying to and from Hawaii saw multi-day delays, including one flight that was 52 hours late.
That's a lot of time to kill at an airport bar.
