Horrible airlines. They claim to save you money, but charge for freaking everything! They charge for a carry on $55, they charge $50 for a check in, and anything over 40lbs, is an additional $30, and more as it goes up! They charge to select a seat, and I'm sure they probably charge you too use the bathroom too. I'm never flying Spirit again, EVER!! Saving $50-100 on the ticket is NOT WORTH IT! I'll gladly pay more for United since they only charge $25 for a check in, nothing for carry on, and allow up to 50lbs. Too bad I can't give 0.5 stars.
