This was my first time flying Frontier. I was surprised by having to pay to have a carry-on bag, which cost an additional $152 round-trip for me and my husband. Also, nothing on-board is free...not even water! They try to get you to reserve your assigned seat, but we just waited and let the airline assign our seats upon check-in, which we did on-line 24-hours in advance. We got seats together because we checked in early, but we could have been separated since we didn't pay extra to reserve seats. So, don't be too impressed with their low fares because you will pay extra to have luggage as a carry-on or a checked bag, and if you are traveling with someone who you must sit next to, the only way to guarantee that is to pay extra to reserve your seats. I suppose the flight itself was fine, and the staff was friendly.
