It was very cold because the air conditioner was on high power, and my son got sick.

It was very cold because the air conditioner was on high power, and my son got sick.

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.

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.

Seats are weirdly bent, I felt hunched the entire time.

Nothing exceptional. No drink of any type, even in first class was provided for the hour and half trip.

Paid for premium economy had no tv the whole time the crew tried to reset/reboot but would not work they said they would put a trouble ticket in for it. We had 3 seats my tv was the only one that didn't work. They cancelled our flight re worked us on another that left us at airport over night on the floor I have a ten year old and a 78 diabetic mother which also had shingles and suffers from nerve pain in legs and back. Requested wheelchair service at all airports after the re route NO wheelchair service was there to help. WORST experience we have ever had. Went to American airlines assistance it was closed. I AM FURIOUS!!! I expect some sort of compensation from this traumatic experience and no need for flying points we don't plan on using American airlines again!!!!

This is by far the worst experience I have had with American Airlines. The start of this trip was a complete disaster. I purposely planned my trip so that I would weather any delays so that I could make very important meeting at the Pentagon. My flight was cancelled because of maintenance and I was put on the first flight the next day but I was late to the meeting. After a long week at the Pentagon I just wanted to go home and my flight home which was early in the day was delayed. Eventually the flight was delayed until the next day. I was not authorized a hotel room because DCA was my point of origin. So I paid for a hotel out of pocket. The flight this morning was boarded then deplaned because the aircraft was hot. The flow of information was not happening in DCA and made it worse when the news was bad. I am going to take a break from American for my next few military flights. Hopefully whatever has been going on with American Airlines will be resolved.

We had a 2 hour delay. The seats were smaller than most other airlines. The person in front of us wanted to lay back and we had to stop her because she was pressing against my girlfriend’s legs. We had to ask her to sit up and not lay back due to the lack of room.

Information when booking said the flight would be with American Airlines but the flight was actualy with British Airways. Check in from Orlando was nice and quick. I agreed to put my cabin case in the checked luggage as it was a full flight. Case came back damaged (unable to put the handle down) so will have to dispose of it. Seats were quite cramped with very little leg room, even for economy. This was the experience of both the outgoing and return flight. Cabin crew were ok and flight time was punctual.

Everything was fine once we actually got on our flight. It was more then annoying they canceled (delayed) our flight. We lost out on a day of our trip along with money on our stay. Plus we had to book another hotel. So expensive.

This flight was canceled and delayed several times without explanation. The plane was freezing cold and no wifi for messaging. Getting off the plane was terribly unorganized and felt like it took forever….

The flight was delayed several times without explanation. The seats were terribly uncomfortable and wifi isn’t included. All these make for a less than ideal flight.

The flights was delayed by hours and it was the firmest landing I have experienced in my life. My back is still sore.

The flight got us safely from point a to point b and on time. For a transatlantic flight that isnt nothing. Flight crew was kind and professional. The seats are super uncomfortable (worse than domestic budget airlines) and the cabin was DIRTY.

Long unexplained delay, uncomfortable back row, long waits for trash collection.

Great service on the plane and by ground staff. great prices. I was able to change seats on the plane. The allocated seats cannot be changed when checkin in online. They have to be done at the airport if you check in at the airport or on the plane by asking a stewardess / steward.

Are Longus was fine. I booked thru Kayak and was unable to get my business class seat early. Sat next to galley. Crew forgot to wake me for breakfast.

I loved how they arrange boarding (starting with people seated in back and moving to the front). Flight crew was very polite and welcoming. Seating was ok, I felt like there was enough leg space however it is noticeable when the passenger in front of you sets their seat back.

Flight staff very friendly and helpful where possible. Late flight and travelling with young child, cabin lights remained on for the duration of the flight which was a little disappointing considering the time of the flight. Overall very happy to travel with Aer Lingus.

Nice to be on a flight that wasn't fully booked so there were only two of us in the three seat row.

The only problem was there are games on the entertaiment system. The guy behind me played poker the entire time and poking the back of my seat. I hope they remove these.

Delayed due to weather... fine. But then the board us. Rows 15 and back had to go down the stairs and back up the back stair entrance to the plane. No assistance offered. Then they inform us that we are delayed for paperwork for an hour. So why did we board? Then, about 45min later they inform us that it'll be another 60-90mins. Really? No wifi, no seat entertainment, no drink or snacks offered. And we were not allowed to deboard.

Great travel. Wonderful experience. Hope to do it again in the near future. God willing

The Lufthansa flight was delayed, and I missed the connecting flight. Lufthansa customer service have not been helpful in rebooking the subsequent flight with Air India (another airline that is part of the Star Alliance). Lufthansa told me it's not their responsibility, and Air India says the PNR is part of Lufthansa, so they are not responsible for rebooking. Lufthansa customer service asked me to contact the counter at Delhi airport, but no one was available there. I am caught between these two airlines, and ultimately, Air India decided to reschedule my flight after 18 hours. I am stranded at Delhi airport. I can't go out because if I do, I can't come back in, and I can't get past security to get food. My 3-year-old and our family stranded here for 12 hours without food and water.

I wasn’t able to make my flight due to Kayak’s inability to simply update my name on my trip from Nick to Nicholas. I would like a refund.

The flight left an hour late and no explanation. Food was basically a few snacks out of bags and tiny cup of soda. Crew was pretty friendly.

United delayed the flight to assist customers to make the connection. The Ohara customs area was overwhelm which created an issue for customers trying to make the Little Rock connection. The delayed allow several customers to make the final flight into Little Rock.

Missed our flight to London and we were put on coach seats to Munich.

Terrible. Missed our flight to Newark as well as our flight to London. Complete disaster

They canceled our flight last minute and we had to get another flight with twice the cost

Dinner was excellent - beef stew, the eggs for breakfast were only ok. It was soooo nice that there were so many options for movies and games.

Captain waited 45 minutes for late passengers boarding from Washington DC to Munich which was nice for them but caused our luggage to miss boarding our connection on to Bucharest. We then did not receive our luggage for about 48 hours after landing which was very inconvenient for our travel.

Poor, we had 1 hour to grab our checked luggage, go through customs, recheck bags and run across terminals to make our United flight. Poorly planned connections.
