Noticed Allegiant Air has a flight out of Des Moines in December when I'm headed to Vegas. It is at a minimum at least half the price of all other one way flights (already booked a cheap return flight). That even includes Southwest. I've read a a lot of not good things about Allegiant, but then searches other airlines for comparison reviews and find bad reviews for others as well. QUESTION: can it really be that bad? It's a non stop flight, so that's also a plus. Can anyone sway me either way who should/shouldn't book with them? Thanks!
