Allegiant Airlines charges you $35 to print out your boarding pass on line, or you can get it at the airport. They also require you to be at the airport 2 hours before your flight leaves. But, if you get to the airport 2 hours before your flight, the ticket counter is understaffed/backed up and you get to the head of the line 50 minutes before you flight leaves; they won't give you a boarding pass. They won't refund your money either. So, even if you do exactly what they tell you, you will be out your money. The won't reschedule you on another flight, either. Don't fly Allegiant Air.
