Do you find that Spirit flights board and deplane faster? People struggling to get overhead bags when I'm feeling very cramped and just want to leave is one of my pet peeves.
It seems faster than average. There are aspects to their service that are horrible; their website, a la carte pricing and "buy your bags" terminology are incomprehensible if you aren't already accustomed to it. But they're cheap, quick and never even ordered any 737 Maxes.
