Of course, know what you're getting into with a budget airline. Frontier charges higher than average prices for bags and charges to reserve most seats. (Some less desirable seats can be reserved in advance for free.)
Frontier's luggage fees can get a little complicated, but you save money by paying for your bags online at the time of booking. That will cost you $30 for a carry-on (personal item is free) or $25 for a checked bag.
It's not for everyone, but if you can deal with being assigned a seat, and you're capable of packing light, fares this low can still be a cheap trip after the fees. Either way, it's certainly better than going to work.
