Salina to travers city was great! But the sept 24 Tranverse city was not! Traverse city to chichago was cancelled, i went to Denver & got to Salina 6 hours later!

See previous note about the passenger in Denver who threw my husband's bag out of the overhead bin in order to maker room for his own. And the flight attendant back up the new passenger.

Could have said yes to a glass of wine 🍷 instead of saying we'll come around in a couple of hours

My flight was delayed about 1 1/2 hours in Chicago, but other then that it was a good flight.

Flight attendant in first class gave poor service (like he didn't want to be there) and food was awful. We sat waiting for gate upon arrival over 45 mins.

Inoperable monitor left no entert for 9 hours. Crew was not helpful Food was awful.

Weather delay in Chicago?. No sense of urgency to make connection in Chicago for our connecting flight that wasn't delayed. Connection was missed.

Overall it was good. I missed my connection but I was put on another flight.

Overall a very poor experience - booked premium economy tickets but due to last minute flight delays , all my itinery went for a toss and had to fly economy class with no access to lounge or any compensation by united airlines to make up for the flight delays . i had expected better experience than that from united.

It was fine, definitely older planes with no charging or anything. There’s no entertainment set up on board, but it is nice that they allow you to access the in flight entertainment from your phone without having to pay for the Wi-Fi and they do offer free texting.

Terrible. Flight delayed for more than 8 hours with only a $12 meal voucher provided for the inconvenience. The airplane did not have breaks on arrival yet they still made us go through the motions and board on time knowing we could not take off then sit for 40+ minutes before having to get of the time. A complete waste of my time. I cannot believe they can stay business with these shenanigans. I’ll avoid this company like the plague moving forward as the lack of accountability is disgraceful.

This was the best 2 flights I have had with American out of SGF. Great crew both flights.

Premium economy seat was decent. As always poor headphones, poor food and beverage, crew is not overly friendly

Excellent - explanations were clear staff was nice and flight was comfortable

Lost bag and 2 days no word leaving for cruise no clothes or stuff

The flight was on time and crew were nice, seats were tight and there was entertainment available

Any flight to ORD after about 2pm this summer has been challenging. Flight was delayed getting in (coming from ORD) and that led to it not leaving before a ground stop due to lightening before they could fuel the plane, and so forth. They made up some time but we were still late in arriving at ORD, and that led to missed connections.

Food was ok, but not as good as I have had before on AA.

Pretty good. The food was just mediocre, the boarding and crew were good.

Worst flight ever. I was suppose to have a 3 1/2 hour layover in Chicago but got to the gate 4 minutes before boarding.

Had to deplane for undisclosed mechanical issue. Landed in Chicago 3 hours late. Food voucher at FLL came just as we were recording. Crew and agents were troopers--better than Spirit last night.

We spent 5 1/2 hours at Ohare cause our flight was diverted cause of rain in the area. We missed appts that we had set on Tuesday and cause we were flying back the next day on the 7am flight we had no time to reschedule anything. Other airlines were landing and taking off fine having no issues. It was only Spirit. Very frustrating flight and I understand why the flights are only around 25-30% full.

Just total easy flight experience!! What could you do better..? Hmmm..? There was nothing I can remember. Spirit was a far more comfortable and easy process than American, United & Delta. I'll always look for Spirit and I've told a few people about, since flying this past trip!! I'm a SPIRIT FAN!! Thank You, SPIRIT AIRLINES!! Very, VERY well done, 100%!! See you...SOON!! -Best, Linda R.

Spirit is a very uncomfortable travel experience. It’s cheap but you are squeezed into the seats like canned meat.

The seat belt was lengthy enough that I did not need an extender. Courteous and helpful flight attendants.

As expected. Nothing jumps out at me as bad or wrong, but the flight was fine. No complaints with pilot or crew. The flight left on time and arrived earlier than stated. Overall, I will continue to plan on flying with Spirit.

Horrible considering I didn’t go and I bought travel insurance and I didn’t receive a refund.

While on the flight we had a delay and had to sit on the plane while maintenance fixed it. It’s ended up taking an hour and a half longer to leave than expected. I had an unruly passenger sitting behind me that vaped during the flight and was rude and loud for the majority of the flight.

Spirit is by far the worst airline to travel with, period. Seats are cardboard, flight attendants need anger management and if you ask for water, you’re basically a criminal. I don’t care how much it costs but I will travel with an airline who actually cares about their customers. Oh and one more thing, the next time your gate agent puts his foot on someone’s baggage's scale, I hope they get what’s coming next, a viral video of your scams. You suck Spirit, do better.

I mean, it’s Spirit. But it was frustrating to have our flight canceled, get bumped to a later flight, and then Spirit was unwilling to check our bag until 4 hours before our flight… tell us we could not sit in the waiting area’s chairs… and really negative experience getting checked in and dropping the bag.
