I just booked my way down to MCO from CLE for April 28th (an 8am non stop flight) yesterday at the airport. When you do that they do not charge the passenger usage fee which is about $18 per ticket one way. I paid $88.80 total for 4 one way tix. I will spend another $100 on 3 checked bags at a later date, but I am happy so far. We used them in May '17 with no issue. Trying them again next month, and again in October for our adults only trip. The total of our 3 trips in 2017 for flights is pretty much what I paid for one trip using Southwest in the past. I also purchased the bags that fit specifically to their flight measurements (18x14x8--if you cant find a bag searching spirit measurements, then search frontier--it will pull up bags that way) They are soft side, no wheels=they actually hold quite a bit of items. We travel a lot for hockey on weekends too, and I use these for our luggage for that too. For our august & october trips we will only be using those personal items bags and not checking any at all. For our longer 10 night trip we buy 3 checked bags each way for 4 people.
