The gate attendant was not clear w message on flight delays.

The flight was over 2 hours late.. once we finally got boarded things were fine

Good flight. Connector flight was delayed so made a short turnaround in Atlanta which was stressful. Otherwise, great crew, Staff in ATL was very informative about the delay and ensured people their connections were fine. Notified the ones that were not. Great communication.

Seat was extremely hard which made even a short 1 hour 20 minute flight fairly uncomfortable.

Only water, tea or coffee served midflight, even to comfort seating. Man next to me needed two seats and took up a portion of my seat and Delta did nothing.

Delta made it easy, comfortable and timely. The crew was fantastic.

Zero updates from the pilots for 30 minutes in the tarmac

Delta flight attendants poorly managed the boarding process and overhead storage. My bag was checked last minute and no claim ticket was provided. My bag is now lost. Complete incompetence by all flight crew involved.

We were told our second flight was canceled, but it was not. We did not receive our bags for two days. I did not have my meds, so I was very sick for the first three days. Our house rental was $5700 for the week. Do the math. It will be difficult for us to fly Delta again.

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

Everything was wonderful, with the exception of boarding a bus to go to our gate. Seems odd, that on both the arrival and departure from Paris we had to drag our bags down stairs, get on a bus to do the next step.

Our flight delayed, due to the incoming flight arriving late from Paris. AF caused us to miss our connecting flight, also booked through Air France directly. They couldn't accommodate us until later that night, and we had to be in AMS earlier than that. They won't do anything else to help us and wanted to charge us more money to rebook us too. Not great service, since it was all their fault.

Seats! The eternal problem in economy. They are like stones!!

Everything is good except the seats are tightened no rooms for the legs,

The plane's pilots, including the captain himself, thanked me for the flight. I know it's just marketing, but it was really nice to see these people. It's a great idea. Airplane food is never "good," but the entire crew and flight organization were top-notch. I really liked Delta, and I think I've traveled all over the world, and that was something new for me. Maybe even the old planes, the B767, but next time I have a choice, Delta will be my first choice. Thank you, a satisfied passenger :)

It was a great experience. The only thing I would have changed was that the bathrooms were never cleaned and they got very dirty.

It was an OK flight with below mediocre service by their flight attendants

Wasted a lot of time trying to find the CDG lounge - it was not next to the connecting flight gate like the Air France staff said.

The only reason the overall rating wasn't "excellent" was due to problems in claiming luggage. The bags are delivered to the main area (Cinta 35) for domestic passengers, but to a DIFFERENT ROOM for international arrivees. After waiting 30 minutes, someone (who didn't appear to be from Air France or the airport) told us to go to another area. There we found our bags, which appeared to have been awaiting us for a while. We had to go through a bag check before leaving the airport. If we had been alerted to this possibility, or better yet, been to go directly to Cinta 34, we could have eliminated quite a bit of waiting.

I did not get my baggage at my final destination..poor coordination with connecting flights with partner airlines (Saudi airways). Also the food was very mediocre.

When booking, the connection times seem fine. But in reality, my two connections were cut short by the first leg being delayed due to issues at the destination (too much traffic going into SFO, ORD) and it became extremely stressful.

Flight and crew were great. Need more legroom and do not allow seats to recline.

Plane congestion resulted in a 1 hr wait from landing to arrival at the gate. This was in addition to also experiencing extreme delays on my incoming flight.

Flight was delayed 14 hours due to DC air show and weather. Missed connection to MUC.

The entertainment options on the seat back video boards were nice.

There was no WiFi available, there were mechanical problems with the plane and we landed at C 124, then the gate was switched to A 26, then all the way back to C126! For a 75 yo woman traveling alone, this was a difficult journey, indeed!

Teeny tiny bathrooms, crew was not realistic about when we'd arrive.

Very bad! They kept delaying my flight and wouldn’t do anything about it

IAD with the archaic people movers is just a place to be avoided.

Cabin was pitch black, even during meal service. The reading lights for seat 2E/F did not work, and seat 2E did not recline.

Flight was on time and the flight crew was exceptional.

My flight was delayed by 8 hours I arrived at airport 4hrs earlier but to see if they can reroute me to get my connecting flt to Hong Kong. They auto rebooked my flt. With no chance. Which I missed this entire reservation through kayak. My next flt they got me on was at 6 am. Misses an entire day of my trip abroad all my accommodations seat assignments were missed and missed adding my TSA precheck to my ticket as well as my vegan meal request so I didnt have meals on any of the flight....so not a comfortable experience. Please help me with accommodations upon my return.

Seat bottom cushions are not good. I’m 165# & they hurt my butt. Plenty of legroom.

The flight attendant was friendly and efficient. The temperature was kept nice and cool. The plane was nice, but filthy. There were visible spills on my tray table. The gate agent was somewhat rude with her announcements and in speaking with other customers.

My flight was delayed. We left at midnight. I got to Greensboro (GSO) at 1am. All of AA's flights in/out of Charlotte always seem to be delayed or canceled. It took me all day on Sunday to get to my destination of Cincinnati from Greensboro. I had to be rerouted through Chicago because my original flight was canceled as the door to plane was closing in GSO. The saddest part is I could have driven and arrived sooner. . . I recognize there is a lot going on that impacts travel. This week it was weather. Yesterday in Cincinnati it was President Trump. But as a frequent flyer, the flight from South Bend to Charlotte always runs late. The subsequent flight to Greensboro is always midnight to 2am. . . I do want to give props the Charlotte boarding crew. They had four flights going out of the same area at the same time. They turned it quickly and mitigated the grumbling from the crowd.

There was a delay with the plan which cause the flight to leave later and once arrived in Chicago there was another delay and some passengers missed their connecting flights

Flight was delayed. Not much information on when the flight would take off. Eventually we were told it was maintenance. App was not giving updates.

The boarding experience was good; $20 for wifi per flight is uncompetitive compared to Delta, Southwest, and others, and puts American lower on my list given similar pricing.

Flight was late and TSA had shut down so (almost) no passengers could get to the gate. American failed to inform TSA to stay open! Needed to get back home so we had to rent a car & drive 13 hours all through the night. It was bad.

For the money that I paid it was a good deal. I sat in the back of the plane and didn't pick a seat and my wife I sat together. Mission accomplished.

Departure was delayed leading to late arrival, 25 min wait for a gate. Basically, missed all our connections & had to be rebooted, which was a very long process.

Plane was extremely delayed, but not all of it was BA fault (some was). Worst part was lack of room - this had as much space as an Allegiant flight. I thought transatlantic usually gave you an extra inch or two, but not this one. Entertainment system sporadically worked and didn’t have great options. Overhead bins are old and tiny, not as good as aunties new planes.

The company that I bought my tickets through, Cheapflightsfares, failed to provide my confirmation information in a timely manner, so I was unable to check on at the country and therefore unable to make my flight. As a matter of fact, I STILL have not received the confirmation. After having read more and more reviews about the company, Cheapflightsfares appears to have scammed hundreds of hopeful travelers out of thousands of dollars. Please look into this company and, for the sake of anyone planning their next trip, stop allowing them to do business through you.

Safe arrival. Improvement on Time efficiency Effective Communication will be great.

Not good. First time flying AA in years and won’t be doing so again. We departed late and missed our connecting flight to Barcelona. As a result we missed the first two days of a Mediterranean cruise. No reason given for the delay. Got rerouted from JFK to Heathrow and then to Barcelona. Flight to Heathrow was delayed causing us to miss the flight to Barcelona again. Routed then to Palmero where we had to purchase transportation and a 2 night hotel stay to pick up the cruise there. Probably cost us $2k plus.

Pretty disappointing. Paid for business class. It was burning up the entire flight. For a 7 hr flight, after the first few hrs. The crew disappeared. Poor service.

CVG to London was a good flight . Thank god the plane was not full . Seating was tighter than any international I’ve taken . We arrived in London 10 minutes early. Had it not been for handicap assistance I would have missed my connection. Had it not been for the extra 10 minutes because we landed early I would have missed my flight . 3 hours and 10 minutes from plane to plane as they were boarding when I arrived . None of that is the fault of British Air but the understaffed and confided security at LHR. Because of this I will never use British Air again unless I don’t land in London . Not the airlines fault but I never want to miss a flight because of the blunder in London . The worst I’ve ever encountered in international travel . Sorry British Air but your home needs better management.

This flight was cancelled at the last minute. We were rebooked on another flight but a day later. We lost a day of our vacation and paid for a night in a hotel we couldn’t use. The flights we were rebooked on (both American) messed up our seating on both flights-we didn’t get the seats we had paid for. All in all, a terrible experience.

Good. The flight was extremely delayed but they rebooked my layover (which took off before we even landed) before we arrived. Second flight made me check my bag but there was plenty of room. Otherwise good experience

Bag was missing when we landed at Cincinnati which caused lot of trouble.
