Love delta smaller commuter plane so no entertainment and paid wifi on MKE-LGA leg was extremely unreliable and slow

Stop changing gates. Stop cancelling flights Stop moving my seat.

Extremely disappointed with Delta. They canceled flight last minute and then I rebooked the other flights and with which were delayed as well

Could not get my connecting flight boarding pass until four hrs before departure! Ver annoying especially since the staff could not explain why!

The flight was flying with 30% capacity. The flight my seat from preferred seating to back of the seat. Even though i can understand that this was to balance the flight weight. The flight attendance decided to do the serving near my seat and in the middle , their noices woke me up from sleep , when i realized that the service has ended and when they were going back asked for a coffee, for which they answered they have completed teh service in my location. That really upset me as they woke me up and also rejected the coffee i asked. I ended up landing with a headache, thanks to the crew that screwed up my travel

I wish the inflight entertainment system options were broader, but overall this was a fantastic crew and I can’t express how cheerful, welcoming, and attentive they were.

Delayed. Hot. Passenger next to me was so large I couldn’t move.

Same experience as the flight from Norfolk to Atlanta where people are boarded in zones that don't make sense. People behind you on the plane will get on before you and they take the luggage space on your row.

The boarding process doesn't make sense since some people that will sit behind your rows are boarded before you and then they take up the luggage space above your head. I then have to wait for people to get off the plane before I can go back to get my luggage.

Everything was good except wifi and a leaking drink chiller. The floor was all wet and my bag was soaked. Did not notice until debarking. Have not heard back from Delta. Even though this was leg one of an international flight in first class, they denied access to their Sky Club - very disappointing!

The boarding was efficient. The entertainment system was a bit unstable but Air France has a good selection of movies.

They lost my bag and I still haven’t received it yet

Communication on the delay, rebooking and how to get a hotel was poor. Mails, airport check-in and transfer desk said different things.

Not consistent with the food quality (I mean taste not freshness)

Food was really mediocre for premium economy in comparison to other airlines… the crew was nowhere to be found… 14 hour flight…

I don’t like that an equipment change caused my seat to change from 23A to 44A. The boarding was also delayed. The crew were excellent, however and very attentive. The food was not bad.

Our flight crew were terrific. And they handle a difficult passenger with finesse.

Excellent, Lima to Paris. But Paris to Amsterdam, delayed, missed my flight and KLM treated its missed flights passengers very badly, terribly bad. No hotel accommodation given. Passengers were told to find their own hotel accommodation and claim at reasonable rate and left the booth and literally with armed Police Officers listening to passengers complains. For three hours, after moving by Uber from hotel to hotel and calling and booking online, no hotel was available. I had to return to the airport and seat/sleep on the benches, suffering the cold, and rats running around until my new allocated flight the next day. It was the most terrible KLM treatment even seen and being a Business Class passenger. Still mentally suffering to date as a result.

3 hour delay but out of their control. App said I get vouchers but when I applied for them, they were nowhere to be found in my account

I bought business class tickets but the seats are exactly like economy with no comfort seats nor an empty seat next to me provided. Very poor, low quality airline.

I paid for a very expensive Business Class seat to and from Cairo Egypt from Charleston SC. There was partnership from states to London using American Airlines. That leg was amazing. The British Airlines leg was a joke. They used the standard no leg room 3 by 3 seats. A tray was put on the middle seat. The trip was 5 hours, from London to Cairo, thus my BC purchase. There was no screen proving tv/movie options, only a small device plug. The fold down tray and the bag of peanuts were typical of normal short run flying. The one toilet was located in the galley. We all got to know each other well. This was my first and last trip with British Airlines. I now understand why they would NEVER give me a seat chart so that I could make a selection.prior to departure. It honestly would not have made a difference, there were less than 50% of occupied seats. Apparently everyone got the memo but me. I have never felt so cheated as with that trip, got to so another going back to London, yeah. I will be sending a letter to customer service and asking for a refund. I will be photos comparing the two BC legs. OH, one more thing. The FC ticket holders got bulkhead and exit row seats. I know they had to be thrilled

Late takeoff, but on time landing. Lost bags, 3 days to find them, still in transit to my location. Power outlets broken, Wi-Fi not working, so much for working on the long flight.

Late! Late and late! More than 1hr 30mn. This sucks when it is the last of a 4 flight journey. I missed my dinner! Which is not nice on Valentine’s Day!!! But better than the gate next to us, the poor Chinese people were rebooked to the next day flight. AA had to call security as it became very heated with the passengers! It was a mess at DFW that afternoon/evening. I wish they had some food for the people who travel as part of international journey. Indigo does it in India and it is fantastic.

Good. For a long flight. The comfort of the seat could be better. Also, the food was « normal » plane food. Not indian plane food unfortunately! Everything else was smooth and great.

The seats were comfortable. So many empty seats allowed for stretching out and sleeping. The onboard entertainment was pretty good. The cabin crew were so kind and kept the passengers well- hydrated, and well fed.

We had American Airlines on our return and it was confusing if we were going with Aa or BA I had 2 different flight numbers and didn’t get our gate until it was boarding. So we were a bit nervous as the which it was

Our Jackson, Mississippi to Dallas Fort Worth flight was delayed on 1/19/26.. This was changed to Jackson to Charlotte in the last minute because of this delay. This started some kind of disconnect between American Airlines and British Airways bookings. We could not go past the passport control in London Heathrow. I had to go to the counter and waited for more than 30 minutes to get a new boarding pass. Problems did not end there. Somehow our entire return flight was canceled by someone. I had to make several phone calls over several days to fix the problem – this was not easy from India. Looks like there was some kind of disconnect between two airlines or some agent did not do it right. I’m anxious to know what went wrong.

My touch screen at my seat wasn't working, the films BA advertised on the website for this flight were not available, and the plane was a little dated, food was good and the staff were good, just let down by the aircraft facilities.

Did not like the seating configuration at all with 2+3+2 in business class. Lacking total privacy and comfort

The flight crew was kind, flexible, and accommodating. The seats on the plane were extremely uncomfortable.
