Seats are uncomfortable and too close together. Also, you missed my connection in Vegas on the way back and I ended up sleeping in the airport, flying back to Burbank instead of LAX and I got home 12 hours late.

Seats are uncomfortable and too close together. Also, you missed my connection in Vegas on the way back and I ended up sleeping in the airport, flying back to Burbank instead of LAX and I got home 12 hours late.

Non-professional acting crew, Very uncomfortable seats…!! Very bad pricing with all the add-ons for seat choice, luggage fees, etc….soon you’ll charge extra for oxygen. The ticket price means Nothing because in the end, the actual amount i paid, i could have and will in the future continue to fly on a real airline…

With this price, I shouldn't complain on anything. I understand I have to pay for every services they provide. The plane could smell a little better. Advise them to use frebeeze to freshen up the interior a little bit.

Terrible. 1st and last flight on Spirit. Check in process was a nightmare. Despite arriving 1.6 hours before flight we had to be pulled from the ridiculously long line to “self check” our bags which took 10 min and required assistance. Seats are very uncomfortable , don’t move, no pockets, no entertainment, no wifi Basically like taking a time capsule back to the 70s. No thank you.

Arrived at 3:45am & found a long line where Spirit employees were standing at the counter but no one was working. Worried if I’d make the flight. Line started moving about 4:15 and got to check my bag at 4:30, realize my flight was at 5:25. Lines thru security were long, got to flight and walked right on. Spirit was cheapest when selected but not after $70/bag and $30/seat - extra $200.

Over 2 hour delay due to “weather” but all other flights were taking off with no issues. We felt lied to the entire time as well.

LA to Seattle was a smooth process. Seattle to LA was delayed more Than 6hrs

Purchasing tickets on their website is upsetting, they take the consumer for a ride...I wanted 2 tickets for me and my friend but we only had one carry on between the two of us. It was impossible to only pay for one - I had to pay for 2 carry ons and blew $50! Shame on their sleazy business practices! The seats in the airplane are shockingly uncomfortable! In the future I will only fly Spirit if I have no other reasonably priced choice. The flight and the crew were good. But still: Go Southwest Airlines!!!

Terrible. Rude flight attendants. Uncomfortable seats. Nickel and dime every service. No in flight entertainment. First and last time to fly spirit.

Way better than I expected. The plane was so clean- the seats seemed brand new; although not super comfortable as they were lightly cushioned.. The crew helped me lift my bags up to the overhead bin which not many airlines do. I knew there would not be internet or food/snacks but you could buy some if you wanted .
