My only issue was my meal was inedible except for the sides.

8.0 ExcellentCarissa, May 2024LUX - CDG

My only issue was my meal was inedible except for the sides.

The check in was horrible. I stood in line for 1 hour to check in with an Air France ticket. Then I was told I had to go to Delta counter onstead to check in instead. It made no sense.

Medíocre. The food wasn't good (although not bad, bad) and the staff wasn't kind. I asked for n extra blanket, the steward never came back, serving us roughly.

They wanted to close counter although they did not provide the wheelchair requested which ended by going alone to transit security and lost long time and they did not want to wait .

They charge me for luggage which is was included on the ticket

Boarding was smooth and on time. The seat was comfortable and the entertainment worked. Staff were gracious.

No bording was given for next trip on same carrier, food was very moderate.

Lost luggage, 2 bags were badly damaged and one of the bags came open.

their gluten free lactose meal is the best, I have never been satisfied with my flight meals. I definitely enjoyed my flight and the chair is very spacious for economy. I'm so glad Delta is my flight way back to NY.

My seat was so uncomfortable, and the headrest was broken. Very very disappointing for the price I paid.

Boarding was terrible. My wife uses a wheel chair and she was in an incredibly hot closed metal cargo box for close to 20 minutes before getting on board

Only water and pretzels served on six hour flight. Did not see crew rest of flight. No video screens and so no wired audio. Poor sound on plan so did not understand anything said by crew. This is a safety issue. Electrical socket did not retain charging block so could not charge phone. No video screen so could not watch movies. Phone is not a substitute.

The food that was offered based on class level of your ticket was absolutely ridiculous and disgusting. They didn't even hot tea to serve, the food was horrible. On our departure flight I was seated in premium plus economy and considering the cost of the flight the food was literally some of the worst I've ever eaten. On the return flight I sat in economy with extra leg room and was given a thin little throw "blanket" and a flimsy little pillow. The air condition was on artic and the seating arrangement wasn't really worth the money. The seat didn't recline good enough and the foot rest was laughable. Total waste.

All flights were on time and boarding was issue free

Water service would be great. The way they board is terrible. Slow passengers first😂😂 They need to smart up a bit

I like the non stop flight to Lagos. The cabin crew were great, the food was alright and the ride was smooth. The downside is there wasn’t wifi connection from Lagos to Washington as stated. The 11hrs flight, became boring at times because of no wifi.

It got me where I needed it to; not much more. It had no competition so that was why I chose it.

Plane didn’t even make it off the ground. We all had to get off and walk to a different terminal (lots of confusion) to get on a different plane. Landed fairly late, connections missed.

One of the best flying experiences I’ve ever had.

The flight cancellation and process for getting a new flight was not that clear. United also had some delays that were unexpected. I am the most disappointed by the fact that I originally bought a Lufthansa ticket, only to be flown by United.

The Flight attendant had an attitude and didn't allow anyone any time to prepare for landing despite being absent throughout the entire trip

The flight was great until towards the end when the flight attendant read an excessively long commercial for purchasing an american airlines credit card. The worst part is that we are doing a lot of traveling this year so i was actually interested in getting the credit card, but I was so annoyed with the long commercial that I completely dismissed the flight attendant bringing around the information. Next time, keep the sales pitch to 10 seconds and then pass around the brochures!!

Nice aircraft. Plane was PACKED full and distance between seats was tight. Had it been more than a two hour flight it would not have been tolerable. I had much more knee space on the JetBlue flight I went out on.

New ridiculous policy by american destroyed my allegiance to american. As a million miler with american, I expected it would be easy to get on an earlier flight when I got to airport earlier than expected, and save a five hour layover. WRONG. The online app would not let me switch flights, So I called, and was promised a call back in 90 minutes. HAH! The customer service desk at DCA said “we no longer have access to changing a flight on our screens. If the app couldn’t do it, I should send a letter to American, but there’s nothing else possible!”

I am tired of being nickel and dimed for seat location, checked luggage and carry on bags. That is why i rarely fly anymore.

It was right on time and crew were very courteous

Great flight. Boarding was efficient and quick. On time departure and smooth flight. Flight arrived early at destination. Good experience.

Literally the worst experience ever and I had my service dog with me. Flight was supposed to leave at 1:51 PM but the plane arrived late. They boarded us around 3 PM and kept us on the plane for an hour saying that due to weather conditions in Miami, we could not takeoff yet. After waiting for an hour, they deplaned. And then they will not give us our bags back that we could just leave and schedule for another flight. Every hour they kept updating saying we have to wait another hour without any explanation as to what was going on. Eventually, I went to customer service to change my ticket, but by the time I made it to the front of the line, they started boarding my flight again. And then when we got onto the flight, they said there were two flight attendants That were past their shift. They kept us on the plane for about another 40 minutes until they told us they had no other flight attendance and had to deplane again. Then I gave us hotel vouchers and told us we would be on a flight at 6 AM the next day. At this point it is about 9 PM. I get to the hotel with my dog, who hasn’t been able to go potty for about eight hours. When I arrived at the hotel, I got a text alert saying my flight has been canceled at 6 AM and they moved past to 5 AM, however the hotel shuttle doesn’t leave early enough to make it to the airport for 5 AM flight. So me and some other passengers got a cab after about three hours of sleep to get back to the airport. This was the worst experience ever.

Their computers were down upon arrival to the airport. They were unable to figure out how to board us. We were delayed over an hour and a half.

Delay. Flight was delayed in Washington.knew that connection was impossible as not enough time to switch terminals. The steward would not let me stay the night. So forced to Dallas.late night, after 10pm.hotel checkin was one hour. Passengers lined up only one girl to checkin at comfort inn. No food availability at that time. Had to leave early at 6:30 am to catch a flight at 8:45. Stressfull.

Efficiency was great - on-time takeoff and landing. Baggage arrived at destination (there's always slow baggage handling in Boston.) TAP food is spartan - bring your own. But the efficiency of the airline more than makes up for the mediocre cuisine.

On-time flight. Nothing out of the ordinary. The food offering upfront could be better.

Delayed takeoff was inconvenient. We should have boardrd later. Coffee/ beverage service on a 7:30 flight would have been good.

Flight from Lisbon to Barcelona was ok. Business flight Boston to Lisbon was awful. Attendants should pay more attention to Business Passengers and not be so stingy with water. Worse Business Flight I have ever taken. Food was awful. Cramped for space.

Adequate. You get what you pay for. Absolutely no frills but a cost effective way to travel between European countries.

Disastrous boarding. Entered air bridge only to descend stairs and enter a bus. Plane had insufficient storage, was old and chair recline was damaged. Air stewardess was sullen.

I wish to bring to your attention an incident involving a flight attendant that occurred on my recent journey. The attendant displayed a lack of courtesy, which was concerning. For instance, after accidentally spilling water on a passenger, the attendant dismissed the situation rather than offering a proper apology. Additionally, when I handed over my trash, the attendant reacted negatively because I placed a paper cup on the tray, she told me this doesn't go here and threw it back on my table. It was apparent that she was experiencing a challenging day, which unfortunately impacted the service provided to myself and other passengers. While I understand that everyone can have an off day, it is essential for customer-facing staff to seek support to manage personal stress without it affecting their professional responsibilities.

The flight crew was good, the flight itself was quick and comfortable

Boarding was late by 30 min due to a bus missing to take us to the plane... And then the flight was delayed by about 90 minutes, in a 60 min flight

Very agressive with bags both arrival and departures found minor damage to my luggage including my check bag being broken into nothing of value was in there so I do not believe anything was taken but definitely broken zipper into the outer pockets of suitcase

Will try to not fly with them again. Delays because of weather but got redirected to an airport where I could not make connection.

Staff didn’t care in business class. Closed the door on my mom while she was on the jetbridge and flight attendant told me she would make it from the connecting flight. They lied. My luggage was damaged on arrival. No success in filing damage claim.

Crew was super rude in business class. Not friendly or helpful. Luggage was damaged and was told to file with United and that was unsuccessful.

The connection at Frankfurt was chaotic and nearly missed the flight to Atlanta. They made was wait for busses to transfer and it took ages

There was a screaming child just behind our seats. This prevented us from getting any sleep during the night!!

my flight was at 3:45 after that they delayed to 4:40 I have transit from Chicago to Frankfurt and Frankfurt to vina airport from vina to Erbil buy the Time I come to Frankfort my other flight left me I have to stay at airport all day with my 5 kids ask for help no one help me I spent at airport almost $450 just for food was horrible flight ever I call and ask for hotel from united customer service they been telling me we can’t provide any hotel I need some refund or fixed my flight when I return to America need some one respond my email

My experience would have been greatly improved by arriving on time to connect to my Porto flight. The staff that dealt with the aftermath of the late arrival evidently booked my group into a hotel in Frankfurt. This reduced my time in Porto Portugal a day and half. I do want to commend Jorge Klein for his hard work. He spent a great deal.of time trying to rebook the flight and he eventually did rebook for the next day and did provide accommodations for me overnight. This was a big issue for me and the group I traveled. The rest of the trip was good.

Not your fault…..didn’t get my drink until just before landing….bumpy flight.

Boarding was a zoo. London ground crew was useless. Poor communication regarding where to line up. We were group 2, and everyone was jammed in together. Ground crew didn’t seem to care.

We liked the direct flight from Frankfurt to Orlando, however, it was a little confusing as I thought I was traveling with Lufthansa from Izmir- Frankfurt-Orlando. We were not able to check in online twenty-four hours before the flight from Izmir. One lady in our group wanted to check two suitcases in Izmir, but was not allowed to do so. She was allowed to take the extra bag into the cablin. Others in our group were able to check two bags. In Frankfurt several in our group were given stand-by boarding tickets, which worried them. Everyone eventually was allowed to board, but it caused them to worry. I didn't have any of those problem.
