we were late due to plane's late arrival at the gate and then there was a glitch with a button or something that had to be fixed and we waited for a tech to do that . The flight was very bumpy and totally not anything to do with the plane or crew. Just saying what was a bit miserable and kind of worrisome give then recent circumstances with the planes. Nothing fell off or onto anything during the flight of take off and landing so I count myself lucky to have gotten to my destination there and back safely. Thank you for asking

The reduced size overhead compartments were a surprise. They keep getting smaller and smaller while amenities keep getting fewer.

My flight was on schedule, ground crew looks overworked, flight crew was great but refreshments could be better. The plane was clean and fairly new. Seats were comfortable but leg room was tight.

My flight was delayed in Fairbanks by 45 minutes with no explanation. My next flight was delayed 3 hours in Anchorage then cancelled altogether. Alaska Airlines App was not helpful as it auto-booked me to reach home 2 days later than planed. And I had to fly back to Fairbanks if I wanted to continue with that change. The only real assistance I received was from the Alaska Airlines gate counter supervisor. She was able to get me home one day earlier. This was my 1st experience with Alaska Airlines and it will be my last.

I'm a tall guy. Fortunately I was able to find seating in the emergency rows that gave me a couple more inches of room. My return flight a few days later, I wasn't as fortunate. Very painfully and uncomfortable return flight.

I think the pilots deserve most of the credit, the flight was smooth and they got us to Denver in a major winter storm when many of the airlines cancelled on other people . Alaska has my loyalty- must have better more capable pilots. Was on 720 - Seattle- Denver. The crew was alright, one of the stewards was obnoxious about applying for a credit cards she went on and on about how much she used hers- it was over the top and a turn off.

Always reliable customer service. Especially, the extra care on a long flight back to the Mainlaind.

Good flight. Pilot kept us well informed and attendants did a great job. Negatives:,1) little snack packs are far too expensice; 2) arrived early but waited 1/2 hr+ to get to our gate to deplane!

Midway through the flight the stewardess moved a man from the back of the plane to the empty seat next to me, since I was sleeping I had not voiced a preferance either way. The stewardess woke me up to say I could move to the back of the plane if I objected to the man sitting next to me, at which point I simply asked "Why?" she was speechless and quickly returned to her duties. It was a strange encounter that seemed to make no sense, even now in reflection.

Great ! The counter staffs in Boston helped me to wrap my broken luggage with a plastic bag to prevent my stuffs falling out.

Boarding was a sh!t show. JFK BOARDING was awful. The agent called three sections at a time Clogging the area then yelling at people to not block the walk way. How are you going to call delta one , premium select and comfort plus at once and the yell at highest paying passengers. Need to do a lot better and the flight attendants in the galley need to understand that their voices travel. They were talking about others and everyone in the cabin heard them

Uncomfortable seats on 14 hour flight. Mediocre food. On time and great crew.

MSP to Atlanta was much better than Atlanta to St. Kitts. Paid $180 each for myself and wife for Delta comfort from Atlanta to St. Kitts. Seats were more narrow and obviously old and worn out. Tailbone is killing me. Seat would not recline. Seats behind reclined and we were not an exit row or in front of an exit row. Entertainment did not work in that the movie jumped forward and back and there was no audio. The plug in the arm rest was loose. Flight attendant tried “resetting” the video for my seat but no good. She never checked back. Someone else near me had the same issue. Touch screen was unresponsive. No where near as comfortable as MSP to Atlanta flight. 3 plus hrs. flight time without the basic amenities and not even remotely close to comfortable but paid for Comfort plus. I will be very disappointed if I have the same on my return “Comfort Plus” flight St. Kitts to Atlanta. At the very least my wife and I should be refunded for round trip “Comfort Plus” charges. Please feel free to contact me directly for more details.

public website still broken for years randomly blocking browsers with privacy options active after loading a page maybe once. check-in on laptop was almost impossible but eventually randomly worked. had to print pass at airport since couldn't get back in to load digital pass on mobile firefox or chrome. red eye flight so smooth onboarding, plenty of room to spread out, easy offboarding. onboard wifi instructions mention vpn can cause problems connecting but fails to also mention private dns. no printed or built in menu list, seems weird to require personal device to point at qr code link for menu which does not even allow direct ordering. people with health condition risk related dietary restrictions trying to avoid for example cholesterol and sugar are left guessing what they can order either way without nutritional info highlights (cranberry juice was minute maid cocktail with as much suger as typical can of soda). tap to pay wasn't working and always seems sketchy to manually enter card info. good movie variety, so limited tv was okay.

Great experience overall. Check in at Austin was congested as they only have about 6 check in kiosks, one was broken, and there was a lot of Spring Break travelers.

The main person that was coordinating everything was a short white/light skin Spanish man and he was very rude. It honestly made me feel like it was everyone’s First day at work. His announcements were very not reasonable and they did not make sense. The stewardess on the flight that made the announcements she didn’t even know what she was talking about she sounded inebriated. There were no snacks or drinks on our flight there wasn’t even much turbulence. This flight was not enjoyable nor was it what a Delta flight should be and just this past week I flew with Delta 3 times.

The landing was bad and the hostess came two times and i was sleeping but when she served the person that nexts to me I woke up and she didn’t even asked me if I need any drink or snacks two times!!!!

The helpful attitude of the staff, and being a wheelchair passenger everyone was helpful and understanding. The trip was made comfortable by the upgraded seat which was given without my request, that was a great surprise. Thank you Delta.

Mario was great. Made a night flight on a small aircraft pleasant and memorable.

It was great I love flying Delta and have never had a bad experience with them

737 Max was leaking water into the cabin through the windows. Overhead bins opened on landing. Bad bad plane.

I was not able to buy food in the flight. They refer to include your Credit card in the APP, and if you are not from USA (i have a credit card form Canada) it is not possible

The plane boarded and deplaned twice before the crew timed out. Flight was 7 hours late departing. Horrible experience!

Over two hours wait to get wheelchair assistance from arrival to the departure gate for LA was unreasonable even though there appreared to be heavy demand.

Everything was very good. Boarding and takeoff were on time and organized. Had a good flight

Wouldn’t let me check in said couldn’t find a ticket had to wait very long Time

Awful…flight was delayed more than 12hrs, missed all connections to Fort Wayne, IN, had to get flight to another city 2 hours from my destination, flight was again delayed by 40 mins because they did not have enough fuel, again missed a connection, finally arrived in Indiana at 11pm…but before my 2 hour drive home, ay, no Five That Our Luggage Never Made On The plane and Still In Chicago

Other than the two hour delay, it was fine. Of course they were very professional and kept us informed throughout the whole delay..

Wheelchair assistance was not complete. The person left me at the departure gate without informing the groundstaff of my requirements. I had to walk to the departure counter to ask for help to reach the plane door. The crew informed me that in future they were not allowed to help passengers like me, senior citizen and Wheelchair passenger with placing their carry on bags in the overhead compartments!

Crew is way too many times on the intercom re explaining the same thing

The 2 hour delay was frustrating but our crew did a great job getting us out quickly and keeping communication especially with the people who had connecting flights

Got a much appreciated surprise upgrade to an exit row and the crew was very friendly and helpful.

The only problem experienced was a ground stop in Chicago due to weather. But the crew handled everything professionally. They prioritized rebooking those passengers who had connecting flights and then deplaning the other passengers. When the hold was lifted, they efficiently re-boarded all the passengers so that we could depart before our departure limit expired.

The staff was unprofessional and didn’t communicate very well. The boarding process was very disheveled, potentially due to a power outage the previous day but there was no contingency plan to properly get passengers boarded the following day. Once boarded the aircraft stayed on the tarmac for over 45 minutes due to high winds. The communication was sporadic but an announcement was finally made an additional 30 minutes later that the flight was cancelled but we couldn’t get off the plane. Prior to deplaning one of the gate agents came on the plane and made an announcement for everyone to pickup their checked bags and take a card to rebook a new reservation because they didn’t have adequate staff. Flights were missed, passengers went to different airports and there was little to no assistance from AA.

Absolutely filthy flight and not equipped for a trans US

Everything was on time; the flight attendants and the gate personnel were very pleasant and helpful.

I had trouble finding a boarding pass because I had an hour between Flights and American did not see my flight I believe because I was ticketed through KAYAK. I did not have enough time to go to the desk before boarding so I went to the desk and told them while I was boarding and they had a boarding pass for me within three minutes. Nice. I paid extra to have more legroom and it is definitely worth it for a six hour flight. I would’ve paid for a decent dinner, but they didn’t offer anything but a snack box —not good for six hours.

I have not found it to be easy to set up on Wi-Fi with American Airlines. I don’t know if it is me or poor instructions.

My previous flight was late and did not connect properly. The gate was closed and I missed this flight.

This flight was late and did not meet the connecting flight.

Delayed several times. Flight was to arrive at midnight and it arrive at 3 am. A 3 hour delay is already bad but one that has you arriving in the wee hour is just disruptive and overall unacceptable. The complete lack of restitution is a joke in keeping with Spirit’s reputation of ranking bottom-low in the pecking order.

Awful experience. Both flights were delayed several times with weather but also crew members being the official cause. The vouchers are unusable and insufficient ($50 voucher to fly the same crappy airline is a joke for putting me on a red-eye that landed at 3:00 am). The aircrafts were old and uncomfortable (have a real pocket on the seat, for crying out loud!).

Its so random that they only allow 40 pounds on checked bags when all airlines take 55. They then charge you for each 10 extra pounds, so my checked suitcase was $130 and the flight $30 ... its like whattt, im for sure not traveling with Spirit again

Cancelled my flight last minute and had to end up driving to Texas from Atlanta last minute. I’m going to miss another day of work, drive back to Atlanta , in my own car and spirit doesn’t want to refund the money. First time I tried flying anyone else but delta and I get ripped off . And I had. To pay for seats for a flight that didn’t happen. Usually you could say you get what you pay for but in this case, didn’t get anything and paid for everything never flying spirit again, or even attempting it or thinking about it.

Actual CLT experience was rough. I've never seen the airport as bad in regards to security lines and wait. (For not being a holiday) A lot of folks missed their flight this morning. Spirit is fine. But wasnt offered a beverage somehow. No worries but some how I missed it.

the landing was terrible. the plane touched down and had take off. the plane flew around and landed a second time.i understand the weather might of been the problem. It was a scary experience and no explanation from the captain.

Flight was canceled and rebooked for the next day. Had to cancel the entire vacation.

It wasn’t as horrible as I would have expected, however, to not provide water and change so much for bags is a ripoff to say the least.

Flight from Tampa to Houston was canceled. SPIRIT rebooked me and they double booked my seat. Conclusion I COULD NOT TRAVEL TO HOUSTON. I MISSED MY GRANDDAUGHTER BIRTHDAY. I would not recommend this company. I will file a complaint. I will never consider SPIRIT as an airline . It’s a faker.

I like strict carry on policy. Quick to board, quick to leave. Less time at gate and get there quicker
