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.

Ongoing flight was delayed. Staff at bag recheck was able to get us on an earlier flight. With only 20 minutes till take off we feared our bags would not make the new earlier flight. We were most delighted that they did and were there when we landed. Delta came through

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.

Connecting flights were poor,especially in Naples.our Lufthansa air bus was a joke.way too small for that long of a flight.no room at all.couldn’t even get out of the seats to move around or go to the bathrooms.we thought we were getting an actual air bus,double decker.i will never fly that long in a plane like that again.kind of misleading to call it an air bus.we actually had more room on our buses that we used.

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.

They have trouble to keep their flights in schedule. Seems not having enough staff to provide appropriate customer service. Lacking real agents on site to help customers. Have to use QR code/web site/call to be able to talk to real person can help you - and you may have to punch though series of options first, then hold until someone assist you. Similar for baggage claim, no real agent onsite helping if you missing luggage, not like other airline next to UA desk having staff there even after midnight to assist customers.

United is my favorite and I always try to fly United. I feel like this crew didn’t mesh well together.

Our flight was delayed three times. It took us 17 hours to get home.

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!!!!

The flight was sequentially delayed until it reached two hours. Apparently one pilot failed to show up.

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.

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.

Internet service was erratic. Crew service was poor and slow. My luggage on this non-stop flight was lost and not recovered

Terrible. I didn’t fly and I had an important meeting the next day.

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.

The trip was good except for the delay that caused a connection issue in Chicago.

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

The flight was wondering, especially the special assistance from airplane to airplane!

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

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.

The worst experience of my life and I have been flying for 33 years

We were very upset when we checked in for our flight to be charged 208,00 euro for luggage fees when the site clearly states we are authorized one checked bag each and one carry-on. We have never experienced anything like this with Lufthansa and are very disappointed. We should be reimbursed this erroneous charge. I can forward all receipts once I am able to scan the them.

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.

Check in in Albuquerque was awful. The people were great but they were over loaded. The procedures were terrible. We got through fine but it took 90+ minutes.

Every host and pilot were very professional. My next flight would be upgraded from economy to the next group.

I asked for a window seat and when I got on the plane 24A did not have a window so was very not happy, but good and entertainment was good and the staff was very good, so the only complaint was the seating.

Flights were actually with Aer Lingus outward and American Airlines & Aer Lingus on the return journey. Outward flight with Aer Lingus was good but the return flight with them was not so good as our seats were in a poor condition (15A & 15C) and looked like they needed replacing! The American Airlines flight from Miami to JFK New York was good and the seats were very comfortable and spacious (32D & 32E)

Awful. Flight delayed and we missed our long flight to Rome. It has been a nightmare and we have still not arrived. It was NOT a weather delay, just poor planning by AA

My seat was in a good row. In our section it was the first row. But it was difficult tooperate seat entertainment features > table, screen, even though I often fly.

Boarding was as fast and efficient as possible. The flight crew were amazing and extremely friendly. We enjoyed our flight.

There was nothing to like besides the crew. The comfort of the airplane was poor (seat did not work properly and it was not comfortable). The “entertainment” system did not work! On a flight that last nearly eight hours, (which is advertised as having excellent entertainment options), that is unacceptable! Passengers should have been given free WiFi for the flight. The food served on the flight was below school lunch grade food. (With one exception, the ice cream snack). The chicken entree was tough and nearly impossible to cut and eat. The “pizza” served later in the flight was worse. The chicken pizza had a dry crust and the “toppings” were equally not enjoyable. The amount of chicken and cheese were almost non existent. Overall not a flight we would want to repeat!!

There was a problem in the luggage because there were not porters

2-1/2 hours on tarmac after arrival to DFW, lost connection to London, 3 hours wait for customer assistance, stayed on our own account in DFW, no replacement flight for 5 days, had to cancel the entire travel and return to Monterrey today.

My worst flying experience so far. This flight was delayed a total of 42 hours and diverted to New York before it was finally cancelled. It was delayed 4 and a half hours in London. As we were scanning our boarding passes at the gate they advised that the flight was being diverted to JFK since the delays caused us to missed the open hours for Charlotte international customs and immigration. We were assured multiple times by airport personnel, flight attendants, and the Pilot that we would land at JFK go through customs and immigration and then reboard the plane to fly to Charlotte in the same night. When we landed in New York the pilot advised us as we were retrieving our carry on luggage that we were delayed till 10am the next morning and to see guest services to get a room for the night. During this time I had to purchase a room for a family member in Charlotte which drove over 4 and a half hours to pick us up from Charlotte. This could have been avoided if American Airlines had been up front about the delay. Then after standing in line for over 2 and a half hours at guest services we were taken by taxi to a hotel 30 minutes out of the way. Luckily I looked for other flights that night and found one at 8 am to get on. The initial flight which we were scheduled to fly to charlotte in was delayed 12 more times and was finally cancelled 42 hours after it was supposed to land. I am unaware of what happened to the guest that were supposed to fly on the flight after we were placed on another flight but 42 hours in delays for a direct flight is absolutely ridiculous.
