3 hours late and all they have is was a $12 meal voucher. That’s not even enough to cover fast food.

3 hours late and all they have is was a $12 meal voucher. That’s not even enough to cover fast food.

Among the poorest flights I’ve had with Delta in a while. Entertainment system failed completely on a 7.5 hr flight. Crew seemed distracted and not the normal friendly crew. Flight overbooked it seemed… very crowded.

If I can, I always fly Delta. I’ve found their service to always be reliable and pleasant.

You could have not cancelled the flight (AA, which I will be flying from now on) left for BOS despite the fictitious weather issues (that no one in my Boston family could see). You could have rebooked my direct flight to another direct flight instead of sending me though JFK, the worst US airport after O’Hara You could have rebooked me on a Main Cabin seat (like the one I paid for in my original ticket instead of putting me a the last row on JFK->BOS leg, pocketing the difference in ticket price But I do not really care whether you will ever do that in a future because in a future neither I nor anyone from my company (unless they pay out of pocket) nor an of my clients and partners (if they heed my advice) will ever be caught dead on any of Delta flights

Really bad baggage handling. Had my Rimowa bag badly damaged at the latches.

It was pretty good I was worried with the short Layover that I might not catch my connection but the gate was there

It was good until there was a 3 hour delay because there was not any pilots to fly the plane.

There was plenty of overhead room but half of the passengers were told they had to check their carryon bags. My partner and I checked in as early as possible and our seats were split across the aisle.

Friendly flight attendants. Comfort plus seats were very comfortable and had lots of leg room. 10A and 10 B.

I've flown many many times on Northwest and then Delta. The crew on this flight were absolutely the best I've had the pleasure of being looked after by.

The entertainment wasn’t playing in the app or online.

Lady was a bit rude during boarding and I was being nice to her.

Why does it have to be painful to fly long distances?

It is a modern tragedy that any airline expects you to travel for 14 hours in such discomfort and that the only way to add comfort is exorbitant prices. I was in pain by the time we landed. Shameful.

Original plane sidelined. Had to wait an hour for replacement.

Crew was very cooperative and professional. Passenger's first checked in bag should be free.

No real agent onsite helping you for missing luggage there. Not like the other airline next to UA desk, they have staff attending in their desk assisting answer/helping luggage issue, even after midnight.

Horrible, the flights kept delaying, so it is obvious that we won't be able to make it to the next connection. No easier/real agent on site to help you figure this out. UA agent on other counters refuse to assist you and direct us to use the QR code/call customer service. So inefficient and poor. While technology seems convenient, but it's not the best interest/experience for customers need help while there is active issue need assistance.

Food is very bad and entertint not too many options ... flight attendet service is not good

After the morning frenzy of 35 min wait through CLT security at 4;30 AM, it was nice to have a smooth pleasant boarding experience. This 6:30 AM flight was not full. We were able to get seated swiftly and took off promptly. Nice touch they distributed the old fashioned headsets with 8 mm jacks. Snacks were decent and arrival was uneventful.

As an advantage member I found the experience very positive

The flight from Amsterdam to Dallas was great, ok food, good service, great entertainment. But Dallas to SF was very tiring because of two hour delay inside the airplane waiting for AA paper work in 99 degrees in the sun. We had no oxygen and the pilot had to ask everyone to blast the AC because it was getting too hot inside the cabin.

American Airlines switched aircrafts for some reason and the new plane had to be checked, It took an hour for this while we were on the plane parked. But then we waited one more hour for an officer to come and fill out paperwork so that he could ok the plane or fly it himself, something of that nature. It was 99 degrees in Dallas and we were cooking inside the plane. The pilot had to ask everyone to shut the window shutters and open the air full blow because it was too hot inside the cabin and smelled like gasoline. Worse was that when I bought the ticket, the third party seller called to insist in buying insurance for this flight. I told them no because I was not going to save any money after all, so I made it to SF somehow by a miracle. Why buy insurance when the airlines are responsible for any delay, cancelation, or problem. Please advice third party sellers like Underpricer to not call and try to sell insurance at $100 per passenger.

As a disabled passenger the arrangements for getting me to the plane and onto the plane were excellent as was the reception and arrangements at Chicago.

We left our child’s tablet on our seat 12 B on the plane and we can’t get a hold of anyone to try to get help locating the tablet.

My flight was cancelled after a 7 hour delay. I am awaiting a refund.

Ability to select seating would be nice. We were family of three and they had us seated back to back and one of us on the other side of the plane??? That is pretty goofy. Especially when tickets were placed two months in advance.

My son and I are 193 cm tall. We had reserved and paid for seats with extra leg room towards the front of the cabin. The day of the flight, we learned that Iberia had changed aircraft. We were assigned regular seats way back in the cabin. When we landed from our first leg we spoke with agents at the gate and we were told that they couldn’t improve our seats because the flight was full.

I am quite satisfied. The flight was on time and landed early. Staff was friendly.

Needed more info on connecting flight. Late flight made very short connection. Lost luggage that we still do not have!
