Pros: "I flew on a basic economy fare (I understand the restrictions) and was seated in Economy Comfort +, so that was appreciated."
Cons: "I could see on the Fly Delta app that I had been placed in seat 10B, but neither the app nor my boarding pass gave me a group to board with, so I assumed that I needed to board with group 3, which necessitated gate-checking my rollerboard bag. Only when I approached the gate to board did I notice on the info screen that I had been "upgraded" to Comfort + and granted boarding with the Sky Priority group. I wish this had been clearer so I could have avoided waiting to board and gate-checking my bag. Minor inconvenience but room for improvement on Delta's part."
Pros: "This was not my original transfer flight but everyone was much nicer and helpful than serious and being rude. Love Delta, I did not flight United because I wouldn’t have met my United flight once landing in ATL. The Young African American woman who was at the gate was amazing and so reassuring that I would make my flight to Chicago. Would book Delta, just because of how nice she was to me."

Delta remains the best."

Cons: "Checking a bag, delta did not have enough crew to get everyone thru to their flights. We waited for 80 minutes inline to check a bag. Then we ran to the gate inky to find the gate was closed less than 2 minutes before we arrived. At least 20 others also missed the plane because of the lack of crew and long lines checking bags. It was frustrating, irritating, uncaring crew checking in, and a bit rude. Then on of my checked luggage was lost enroute - which made getting off the flights even later which made me miss a meeting that I was scheduled to be at. All because you didn't have the crew needed to check in."

The flight attendant laughingly said "The only two things that are free on this flight are the bathroom and the trash collection." On my flight back from Chicago, I ordered a double, neat Buffalo Trace to celebrate the fact that I'll never fly Spirit again. At least they have their humor showing right in their slogan: "Less money. More go." Yep, less money for me, and now much less go."
Cons: "I didn't like anything. Will never book with Kayak or spirit. My flight from Chicago to Minneapolis was cancelled and I have still not got my refund. Pathetic!"
Cons: "Myself and fifteen year old daughter exited plane from Ft. Myers to grab a quick bite to eat and upon returning to same plane with printed boarding passes and assigned seats our boarding passes did not scan correctly. At this time there was about 30 or so people behind us to board as there was plenty of time. We were asked to step aside and a employee was trying to figure things out. In the meantime ALL people in line were allowed on plane even though several had problems but were quickly fixed! At last second we were told to board the plane and try to find two seats. Only one was left on flight and we were told they had to leave and sorry but we must exit plane! Worst I have ever been treated by an airline ever in all my years of travel! I did get some money compensation, rented a car and drove 13 hours to Chicago! Awful way to end a vacation!"
Cons: "paying for my bag"
Pros: "Funny flight attendant. Left on time. Arrived 20 minutes early both ways."
Cons: "You pay for food but ate before I boarded, so no problem. Entertainment, brought book/magazine so no problem. They charge for luggage and carry on, but I'm learning to pack lighter and just packed everything into my free bag (backpack ).Because of cheap tickets prices,I'm ok with their bag fees."
Pros: "The dared"
Cons: "The 1.5 hour delay on a late night flight back to Chicago for no apparent reason."
Cons: "Rip off airline...not worth the cheap price to then pay $55 for a carry on bag...plus you have to pay for drinks on the plane."
Cons: "That they charged me for the carry on bags on both flights! i thought it was the cheapest ticket but turned out that they take extra charges for everything, which makes my total payment for the flight as paying for two tickets at the same price!"

Cons: "Couldn't pay for bags during Kayak purchase. Ended up paying full priced on bags even after I joined their $9 club."
Pros: "The flight was fine."

Pros: "Short flights"
Cons: "The entire process, from start to finish. They really didn't do anything right"
Cons: "Wish the people would talk slower when making announcements."
Pros: "Efficient boarding process, some jokes with safety info."
Cons: "Seat back in front of me was clearly not clean. Child behind me kept hitting or kicking the seat and the seat was thin, so I could feel everything. Food offerings were snacks, not healthy food."
Cons: "Charge for one bag was $54"
Cons: "The flight was delayed two hours, it took me 45 minutes to check in online, the flight staff was horrible, half the plane received drinks the other half didn't, they left the seat belt light on the whole time in the air. Also it sounded like the plane needed to be checked out it made this loud horrible sounds during take off and landing Never again will fly with this airline"
Cons: "Our flight was delayed 3 hours, our connections were rerouted so we got to Vegas 12 hours later than planned, and the restaurants in the airport refused to take the free meal voucher."
Pros: "I made it alive"
Cons: "Everything else"
Cons: "1. The flight was delayed by 1 hr 2. After landing in Chicago, passengers were not allowed to disembark for 45 min 3. The luggage was lost 4.

Cons: "Seats were too narrow and too close together"
Pros: "The attendants seemed nice. Very Polite."
Cons: "Everything Flight I had with Spirit was late. Knees were jammed packed onto the back of the other seat. Not a airline for anyone over 6ft unless you pay $30 extra for extra space."
Pros: "This was definitely the worst experience I have ever had with an airline. Words alone can not describe the amount of stress Spirit put me through, and I doubt I have enough space to adequately express the reason for my resenyment toward them. If you think Spirit Airlines is a bargain you are sorely mistaken and I would caution ALL prospective travelers considering their services."
Pros: "Quick boarding."
Cons: "Spirit does not participate in TSA Precheck = bad. Spirit charges for everything and it's beyond annoying. Spirit requires tickets to be printed. What year is it?"
