Flight was delayed due to weather. Crew did a nice job of making us comfortable. No complain complaints.

Our bag was lost so that made unnecessary chaos On our trip

Delta is my preferred airline. I've traveled with them for years. On time in most cases, good communication, easy to use app. Most planes are pretty nice. I was on a CRJ 700/900 however, which was pretty badly aged inside and needed a refresh. No infotainment, unreliable wifi, best to download before boarding or bring a book. Food choices are really just snacks on this flight, nice variety but about what you'd expect. Great staff and prompt in departure and early arrival too. Overall quite satisfied.

Crew was friendly Love the entertainment in the seat head rest.

Delta flight was on time, seats were comfortable, and crew was nice.

This had nothing to do with Delta… The flights were on time and flawless. The service was excellent. We purchased seats in (aisle/middle) comfort plus since this was a cross country flight. Unfortunately, the woman seated at the window was 300+ pounds and, as might be expected, covered up about a third of the middle seat also. there was absolutely nothing that Delta could have done about that… I just don’t know what the answer should be. If you purchase a seat, you should should be able to use the entire seat and not just the portion that someone else is not sitting/oozing in. Disappointing…there should be something that could be done….I'm just not sure what solution could be.

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.

It was an overnight flight and I desperately needed coffee before we landed, but Delta does only one beverage service, and that is shortly after takeoff, not before landing at 5 am.

A little bumpy ride . No food was being provided due the the turbulence. That was ok it was a short flight to my standards.

Everything is good except the dinner and breakfast. The sandwich is very delicious. Toilet is clean, I only use one of them. Flight attendants are very nice. 👍👍

A bit rush for transit. Food and entertainment are not available

Boarding was a little difficult. The gate area at O'Hare was very small and crowded due to multiple gates in the area. Could not hear the intercom, so had to rely on signage to see when my group was boarding and the signage was blocked by passengers standing in the gate. Flight was great and we arrived in Montreal on time.

Multiple delays and not straight answer from the United team

For economy, it was very good. Staff was great, they even let some of us change seats for more leg room... Put an empty seat between us which was fantastic for a 12hr flight. Onboard entertainment was excellent, I think over 200 choices of movies/tv/etc The bad was the barely/nonfunctional wifi that cost either $16.99 or 1700 miles (full flight). It was atrocious... Definitely the worst of the last 3 long haul major airlines I was on the last few months.

Stewardess spilled orange juice on my clothes/seat no help no apology just threw napkins at me to clean the mess up. Not Happy.

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

The plane pushed back from the gate on time. However, it stopped on the ramp, and we waited for over 20 minutes before the aircraft pulled back to the gate. Apparently, something of importance had to be removed from the aircraft by the gate agent. I found this to be odd. The delay was not significant, but I felt that whatever was on the aircraft that had to be taken off, should’ve been done before we pushed back from the gate.

I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.

Electric plugs didn't work. Entertainment system wasn't working

Excellent from start to finish. All staff members were amazing!

Excellent. Although they used to greet me as a mosaic member and provide a free drink, early boarding helps me to keep coming back to JetBlue.

Cancelled flight with no specific instructions to get a boarding pass for another flight. The whole flight of people were in line for an hour because there was only 1 person to help at the desk. This was unusual for JetBlue.

It was too hot in the cabin. The AC did not help.

Except for the 28 minute delay leaving and the earlier reschedule to a later takeoff time the flight was good.

Loved the leg room and tvs screens on the seats and free WiFi. Wish the price was lower and could save by rebooking

No music app working: no economy meal on five hour flight; hour on tarmac at the end waiting for a gate. Flight itself was smooth and easy.

It took 1-1/2 hours to get our luggage after we landed. That to me is unacceptable

The flight was delayed for 4 hours. Once onboard the crew was wonderful.

Overall was excellent. Will definitely us JetBlue in the future.

really bad they refused to check in luggages that I had purchased, even showing them the transaction receipt from british airways app the staff in miami was MEDIOCRE

Crew was great and responsive. Entertainment quit working with about 4 hours remaining on the flight. My seat cushion was broken.

Not very good , the stewardess were unfriendly and they don't like to be bothered. Cos was a night flight and they need to sleep.

British Airways staff are very polite and willing to help.

This particular flight wasn't very full at the back, so there were three seats available for spreading out and getting relatively comfortable

Seating was horrible. Small seats. Access to flight information and extras very iser unfriendly. Kept losing internet after paying for it. Staff in madison was as unprofessional and unhelpful.

There were several issues with this flight. I have flown quite often internationally and I was surprised by the lack of presence of attendants other than meal and drink times. The food was not best but I feel that is the norm. We also had to get off the plane once in London via stairs and bus to the terminal. Anyone who had another flight had to then get another bus to another terminal. This causes me to miss my flight and have to rebook.

The boarding process was a nightmare and though we were traveling business class, we were in Group 2 and the organization was terrible. The Business Class on this flight was crowded and did not feel clean and nice. Overall, I would not travel Business again on the American Airline flight through British Airways Not nearly special enough for the considerable cost .

Not too impressed with them to be honest. They had forgotten my gf meal, despite the fact that the app had notified me that it was sorted. Apparently there is a ‘glitch’ in the system, according to one of the stewardesses, and has been for a while. Also the legroom in economy is way too small (and I’m a slight person) and are very uncomfortable. An extra Internal flight I booked via the app, had not even given me the option to order a meal, so was unaware of that and left without food on a 9 hr. flight !! Don’t think I’ll use AA again after this.

There were several different delays but we ended up being delayed a total of 40 mins or so. It was annoying we had a gate change which made it take longer to leave DFW, and we had to check our carry on. Ugh

The flight from Seattle was delayed, which made me miss my connection to Florence. I was re-booked NINE HOURS LATER!!! That’s basically a vacation day lost. British Airways needs to partner with other airlines when possible to get a more realistic travel time, if delays occur. I realize there aren’t many flights to Florence from London, so I would book differently were I to return. The actual flight from Seattle was very comfortable and the crew was great, no faults there. I enjoy British Airways, this was an anomaly.

The crew could not have been more helpful, my meal was excellent, I slept peacefully until right before landing, and the BA lounge was a godsend. The only negative I encountered was the coffee both on the plane and in the lounge. Not to my taste but that’s a personal preference.

I don’t understand why a reputable airline like BA would delegate their London flights to AA. Makes no sense to me, as most domestic carriers do such a poor job these days. Terminal 3 at LHR is a total dump

Cancelled flight minutes before boarding. Rescheduled flight was two days later

The flight attendants were EXTREMELY personable and appreciated the service, lights going off after dinner (probably the norm, but I haven’t flown evening overnight flights in a while). Thank you!

Business class seats were very dated on my plane. Very little storage, charging ports were not easily accessible, tv screen kept flopping away. Vegetarian food was disappointing: hardly any protein and severely under-seasoned. Crew was lovely.

The food was ok, but not great. They delayed boarding in Portland and did not enforce group boarding. But the crew was excellent, went above and beyond.

The food was pathetic. There wasn't much leg room and recline space for such a long flight. No tea/ coffee for a 2-3 hour connecting flight without purchasing! Really!?

Service was very good. Because I use a cane, I was allowed to use Priority Boarding. Biggest problem was extremely limited leg room in Economy class seats. For airplane food, it was alright.

Was late but that airport/storm fault. Flight was full but comfortable. Food quite nice. Unfortunate that I had a rather miserable attendant, others were much friendlier
