If you're looking for a cheap, convenient flight to Vegas, allegiant air will get you there on a budget. Expect your flight mates to be college kids or bachelor party bound. The seat is cheap for a reason, there is no front pouch in the traditional sense to store glasses, phones or water bottles, instead there is a small slit in the plastic where they have forced the emergency bail out pamphlet and a barf bag. All bags are up charged so be careful upon booking your flight. If you plan on eating or drinking anything on the flight, you will be up charged. $2 for a bottle of water, no other water is available.
However, I booked my flight on Sunday for a departure on Thursday and paid a reasonable amount despite the late booking. I would fly them again.
