Allegiant Air - Do not fly Alegiant Air!!
This airline has excessive fees, hidden charges and horrendous customer service. The cancellation fees for our flight exceeded the booking and our only option was to walk away. The website is ridiculous, with additional charges for everything and I will be amazed if this airline is still in business in a year.
If you don't have any luggage, don't care what seat you get, don't mind flying with an airline who clearly doesn't need you or your business, then go for it!
The bottom line for me is this.. does a company who cares so little about customer service care about the quality and maintenance of its airplanes? My guess would be a solid "no"!!
