The seats are uncomfortable probably the longest flight that I would take on frontier was to Atlanta without a break. I would never take it to LAX out of Fort Lauderdale without a stop.

These people need to do something about their ridiculous bag fees. I paid 75 a piece for two checked bags and because they were 1 and 2 pounds over the ridiculous 40 pounds limit they tried to charge me an extra $100 dollars each. I have to open the bags and remove some items, how about prorate the extra fee per extra pound, a hundred dollars extra it’s just abusive and plain theft.
