Customer service at the gate in the flight was exceptional. On time. Aircraft and seat was decent. Thanks Delta. 💗

It was terrible, if they ran flights on time it would make a big difference.

Great flight. On-time, comfortable, clean aircraft, and offered snacks pre-flight to plan for a potentially turbulent route. I wish there was Wi-Fi an all Delta Aircrafts but for a short flight this is not much of a problem.

Delta seems to be improving in many areas, except they are super bad with the food available. Bring back normal food service on long flights.

If I pay extra for "comfort+" I expect leg room where I can stretch my legs. I was seated with an attendant's seat blocking my feet. Knee space was fine but my feet had less room than the non-"comfort+" seats. Also, don't go cheap on food when you have flights of 3+ hours. It's insulting.

Everything was good except when we're on a 6 hour flight at dinner time and all they offer as part of the fare are little bags of junk food, it's disappointing. Bring back food service without an added price.

I sat in comfort plus. It was fine. Seats were comfortable. I got drinks and snacks.

Crew was nice. Flight was timely. Seats could be better as well as the food considering it’s first class.

Left on time and arrived early this extending our 31 minute transfer. Bags made it also!

Good and consistent Printer in lounge did not work for me :(

I rate it is good we had a 4-hour travel delay at one point but JetBlue gave out food vouchers and travel points credits for another flight so they try to make up for it

Smooth boarding and friendly crew. Unfortunately as soon as we boarded the unit that provides air circulation failed. The pilot informed us and requested maintenance technicians to check it out. The plane became uncomfortably warm without any fresh air coming in. Plus the repair delayed our departure. I am glad the maintenance crew were able to fix the problem. I also was without use of my tv monitor for the first 1/3rd of the trip.

Communication with the customer and stay is important. Staff off with a minor inconvenience but it worked out of course. Also this was a very old Mint Class plane. They snuck this one in on us. The updated aircraft are much better.

The flight itself was fine, but the boarding process was extremely frustrating. There is no one scanning boarding passes - passengers just scan themselves and enter the jetway. By the time my husband and I got on the plane and were halfway to our seats they determined there were too many bags on the plane and everything at that point needed to be checked. This created a lot of unnecessary chaos. They should have alerted people before getting on the plane that they would need to start checking bags instead of waiting until people were already on the plane.

The best flight I’ve had in a while. The plane was like 25% capacity, if that. Smoothest boarding and deplaning process I’ve ever experienced. Wish all flights were this smooth.

I paid for the service of having the right to choose my seat and it was not like that, they put me where they wanted and I explained to one of the staff that they were before boarding and they were very rude. I am traveling with the family and they put us in separate seats.

Everything was great except for some reason crew and ground crew could not figure out how to deal with an electric wheelchair and it delayed us 20-30mins. Was pretty frustrating for passengers and the captain.

Great! I love Jet Blue. My favorite airline! Very efficient, clean and timely.

We were told that our flight would be delayed for 90+ minutes because of weather, so we went to get something to eat only to have them randomly start boarding 15 minutes after the announcement, with no warning.

Entertainment... No earphones passed out. Many including me couldn't use the TV. Legroom was good. Crew was indifferent and a bit surly. Free wifi was a nice convenience. Check in desk location was unknown. Gate number on the boarding passes was wrong.

Plane was was better than th YVR to ORD flight but was a fraction of the distance. Fly your better planes on longer distance flights.

Nothing wrong with the flight itself. But due to 2+ hrs waiting in immigration and the additional security checkup in O’hare, I nearly missed the flight.

They need to improve their boarding process. Group 1 and/or paying first class passengers shouldn't be in the middle of boarding process

late departure due to some unspecified issue with ventilating the cabin. They got it running but it was FREEZING for the whole flight. I asked for a blanket but they didn't provide one. They could not turn up the heat. it was quite miserable.

Excellent staff helping my 96 year old senior promptly with her oxygen needs

Good even though flight was delayed, the crew was prompt and efficient.

I still prefer Delta, but Delta doesn’t fly to State College PA.

Everything was fantastic. Modern plane. All the amenities! Although the paid snacks and meals are pure robbery. Like i understand airlines need to make money, but 11$ USD for an overnight oats with some nuts in it and barely any pieces of apple.... Highway robbery

The flight was bumpy. No Breakfast or coffee was served, not even a bottle of water. The food was okay but odd. Rice with peas instead of couscous with some unknown green thing. United Airlines did not tell me that there was VERY LIMITED HANDICAP SERVICE IN NAPLES. De-plane via 20 aluminum steps. Taken to Van. You must walk into the terminal, find luggage, and then walk out to the rental car pickup spot that is 1 block from the terminal.

Crew did their best but the plane configuration is too tight if you're bigger than an average sardine. Controls for the entertainment system didn't all work. The aircraft hadn't been cleaned in awhile.

I was in a wheelchair and went from international to domestic. I was transferred to several different modes of transport and expected to give a tip at each transfer. I was, although, grateful to get to the gate in time for my flight.

My flight attendant was attentive! The elderly person next to me was flatulent and the flight attendant could see that I was in distress and brought me some face masks

My boarding pass wouldn't pull up in the app very easily and had to really dig through my email. That caused a delay in TSA..

The experience was good! I did not try any food, or in house entertainment. I don’t believe there were any tvs. Nothing major that stood out, but low key and good! Thanks!!

No food, no entertainment. But the flight was really short so maybe they had to skip drinks. I was able to board early ONLY because I am old and decrepit and they let me pre-board. I RESENT your dumping us into category 9 if we do not pay up. And when I paid for a seat I was STILL given 9. The pre-boarding helps. THIS flight was exceptionally smooth, please congratulate the pilots.

I had a TERRIBLE experience with the AA crew. I believe it was disability-related. It’s unlikely I will fly AA again.

Baby cried a lot. Nothing anyone could do about it. Just part of flying.

The flight crew was fantastic! Which the seats had a small TV.

The flight was delayed till next day ! They kept delaying every 30 minutes then after 3 hours they delayed it till next day. We kept waiting in line standing more than an hour to get the hotel and meal vouchers. There was no communication at all. Everything was bad

Smoothe flight. Pilot and crew did a great job. Uncomfortable seat in this jet, felt worn out

Helpful attendants at check-in is very good. The $70 charge for a checked bags I didn't care for.and the constant charges for picking a seat and faster check-in are too much. Please cut the prices by at least 50% would be fantastic!

Absolutely the MOST uncomfortable seat I've EVER had on ANY airline. It should be a criminal act (cruel & unusual punishment). NEVER AGAIN will I travel your airline.

The flight was delayed over an hour and we had to sit on the plane. Crew does not apologize due to the delay. Spirit will NEVER do anything to give a customer a better experience. A child next to me was kicking me the whole time. I don't ever enjoy flying with Spirit.

Easy! As long as you don’t mind no frills, our flight was enjoyable and on time

Fantastic. Had handicapped traveler and they helped us through security, helped with boarding, helped put wheelchair together, and were all very patient. A pleasant change from previous spirit flights I’ve taken. Highly recommend.

No frills, cheap price & flight was on time, I'm happy.

Flight delayed. Seat assignment doesn’t get assign until last minute. Seats don’t recline and very stiff

The flight was delayed, and we waited for more than an hour on the plane.

Could at least have little recline in economy seats and windows to the last row, they were super uncomfortable and lots of chit chat and disturbance from the operation of crew members and other passengers

Was told by one of the helpers at spirit in Detroit that I had to pay for my bag that could fit on the over head bin after I asked her repeatedly well what about the over head bin can’t my bag fit in there she said no I had to check it. Then sent me the long way to the tsa when my gate was the other way. I didn’t have that problem in Chicago.
