EDIT ** AMAZING AIRLINE. READ BOTTOM OF REVIEW FOR TIPS. I missed my flight cuz I was late to the airport and Spirit was VERY accommodating and put me on a different connecting flight for FREE.
READ ALL THE FINE PRINT ON THE WEBSITE BEFORE YOU BOOK AND MEASURE YOUR BAGS BEFOREHAND. If you do this you can avoid the ridiculous baggage and ticketing fees and actually have a pretty good experience.
Sure I didn't get any refreshments and I couldn't recline my seat but the aircraft was impeccably clean and out of the four times I've flown with spirit it's always been on time and there's never been cancellation or delays with this airline. You get what you pay for, and if all you need is to get yourself from point A to point B with little to no luggage and you're on a price crunch, this airline will do the job.
I just personally wouldn't recommend this airline for flights longer than 2 hours since there's no legroom and refreshments.
10/10 would take Spirit airlines again for short trips.
Only shitty part is that my makeup bag and laptop takes up more than half the space in the bag that spirits allows to carry on for free so I basically layer and wear like 3 outfits on top of each other to make room for other things in the bag.
Tip #1: Spirit has a VERY strict policy where you have to be at the gate 15 minutes prior to your flight time, otherwise they won't let you in. All the other airlines like Southwest lets you get on even five minutes prior, but once, I arrived at the gate 14 minutes prior to departure and THEY WOULD NOT OPEN THE DOOR AND LET ME ON THE PLANE. I ended up missing my flight but they put me on the next connecting flight for free.
Tip#2: The free carry on baggage size is exactly 14 x12x16. If your bag goes even a centimeter above that, then you'll have to pay a ridiculous free. I found that most gym bags do the job since they stretch and you can fit in ALOT and even though the actual dimensions are more than the allotted, I always made it fit in the carrying measuring basket they have.
