Food was hood for airline food with good poftion and variety in meals. Frequency of beverage service was very low and amount of soda with meals was inadequate.

bad… no veg food was provided eventhough i pre ordered special meal

Excellent service provided the flight crew. Food and drinks were very good.

Meal options for vegetarians can be provided… Nothing was offered for me for dinner.. crew just said no vegetarian option available and did even bother to provide any alternatives or something to eat.

Cathay has a great reputation, though it's baseline economy seating is nothing to write home about (and SE Asia flight passengers sometime lack 'routine stateside' etiquette). On the other hand, food was great, flight attendants were nice, and price was very good~

I was really impressed with the experience it was my first trip overseas. Nice staff

Not enough food for everyone. . Always run out of food when we ask

The crews were smiling all the time with soft tunes when they spoke; the food was excellent. Thank you!

They charged me $900 to board my flight I already paid for just because I missed my previous flight. I do not recommend this airline by any means.

Not good. Small seats. Not enough food that customers wanted. No special requests were given that i could see. Slow response from flight attendants

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.

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.

Didn't make it dir to delays - no support from United staff

My flight was delayed for a whole day, so I lost a day of my vacation.

flight delayed, was put on another flight after standby queue, luggage was misplaced and arrived to me 3 days later

The baggage handlers broke the handle on my bag that they put under the plane that I checked on the jetway. They traded it out for a less quality bag in Tulsa. But, they said they would try to fix it. Bologna! There was no fixing that bag handle. Someone didn’t care how they treated the bag.

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..

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

seats were way too small. Too short of a flight to offer amenities.

The main problem was delay. The plane was at the gate early and bags were loaded. However, there was no crew for the flight. They were inbound from LGA and had to land and make their way to our gate. It took more than 40 minutes. Then, once the crew arrived and boarded, one of the crew members had to deplane and then a replacement crew member had to be found. It took another 40 minutes or so to get the final crew member. In all, we took off about 2 hours later than our scheduled departure time. Once in the air, the flight was great. Smooth most of the way. The crew was professional and efficient.

Perfect flight. Efficient boarding, on time take off and early arrival. Generally smooth flight.

American is a steady for me. I always get what I expect from them. Sincere effort to get me from one place to another.

I was very good. Service was great. Seating selection was not too good.

Very good. But seat selection was not good. We were put on different rows. Would have been nicer to sit besides each other as a couple.

it was good but would be better if there were more clear directions as to how to clear or circumvent customs in Montreal.

Same problem with the entertainment controls being on top of the armrests than on the previous flight, also a Boeing 737 series.

United was on time. Once I got to the terminal it was fine. The transfer from another terminal was terrible. I had to go up some back stairs that were filthy.

I think it was a very good, left in time and reached in time. Crew was good

I fly all the time for work & am used to seeing "XYZ flight facilitated by XYZ airlines" (or similar) and it's never been an issue. This flight from Edmonton to DFW through Denver was very early - 6 am, international, so at the airport by 3am. The flight was booked on Kayak through Air Canada and the actual flight was supposed to be on United. I didn't receive anything from Air Canada prior to the flight, other than to check in via United app when I tried to find my flight on Air Canada app. The day of, we were all on the plane at 5:45 am, when the pilot came out to let us know that the engine had been leaking for some time, and we were now going to have to deplane and wait for the mechanic to arrive and evaluate. So, we did. Why the flight wasn't cancelled at that point I don't know. After about an hour, sure enough - cancelled, however at that point, it's late already to try and get onto a flight out of Edmonton (YEG) on a weekend, esp. since post-COVID it doesn't seem that YEG has fully recovered in terms of flights and airline availability. Trying to get back to DFW took me the rest of the weekend from Sat am at 6 to Sunday pm - late, included renting a car on my own dime and driving to Calgary (YYC) which has more flight availability, as well as another night's hotel also on my own dime. I found some help on the United app - the chat personnel did try to help find some way home. When I called Air Canada after I couldn't get a flight through United - they were quite rude and short on the phone, letting me know that it was my problem (and United's) not theirs. Since Air Canada booked the ticket and took my money I would expect that if nothing else they would try to be of some help. I am so disappointed in Air Canada and their customer service, btw - my follow-up email to them for some type of resolution or acknowledgement was acknowledged by the system as having been received but as of this point - 5 days later - no response.

Constant delays worked out in our favor but definitely extended our travel day

The crew and the flight was excellent. Captain kept us informed about weather and possibly of turbulence and I appreciated that! The only thing is they didn’t have tv monitors. Other than that, everything was great.

Everything was fine, would have been excellent if there was a tv for the passengers to make the trip go faster. Crew was great and the flight was smooth. Snacks and beverages are always a plus.

Average, boarding was ok, the eye scanner broken mid way through boarding they ahd to do it manually. Did not eat any food, Not even water was offered for free.

Boarding attendant was rude. Crew on the plan were more interested in talking amongst themselves and did not ask parentage if they needed anything or even walk down the isles.

Flight was ok with exception of the multiple delays. As with all Spirit flights, the sights are extremely uncomfortable and lack leg space. However, the price savings is the plus.

I upgraded my ticket at the ticket counter and was not informed of the huge bottleneck at TSA pre check. It took me over an hour to get through the line at this small airport and although I ran to the gate and reached it prior to scheduled departure, it had already pushed pack. I missed the flight. Spirit rebooked me on a flight to Orlando that evening, which would require me to then rent a car and drive to FLL. For scheduling reasons, I determined it be would better to rent a car in Pensacola and drive it to my destination in FLL. Spirit called me that evening and asked me if I was going to board the plane. I explained no, for scheduling reasons. The person apologized and said I would receive a refund, but I have not heard back. Certainly, I ought to be refunded the upgrade I paid for at the counter.

The staff from LAX to New Orleans were rude but the staff from New Orleans to LAX were nice!

Did what they needed to do. Brought us from point A to point B timely and without issue. Boarding through deplaning smooth.

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.

Really nice, flight attendants were so helpful with me and my kids. Extremely grateful, keep up the good work and spirit :)

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