Requested for warm or hot water because of throat pain, it was denied. The entertainment system was hung, requested the crew to turn it off, instead of turning it off they rebooted the device. It was stuck again, no one bothered to check.

Requested for warm or hot water because of throat pain, it was denied. The entertainment system was hung, requested the crew to turn it off, instead of turning it off they rebooted the device. It was stuck again, no one bothered to check.

A couple flight attendants in business class had bad attitudes and provided poor service. They did provide drinks or refill drinks. They talked to certain passengers for long periods of time and ignored others.

Great Brasilia aircraft - not a Boeing 757 like the next part of the flight. Flight from MCI to IAD was great, on-time, comfortable, did I mention that? The flight from IAD to EDI was painful. One of the reasons I won't fly United again? Boeing 757, with a seat pitch and material that was horrendous. Worst aircraft ever, made worse by United sardine-can tight seating. Oh, and the connection window, 45 minutes, really? At IAD, in different concourses? What idiot came up with that flight scenario? Happily, (for me and my travel insurance people) the flight was late (reminiscent of American Airlines). The crew was professional and courteous.

On boarding crew at the airport called in the boarding numbers too early meaning before the previous line was completed resulting in later numbers getting to board ahead. Also she asked those who boarded from number 3 to have the tags in their carry-on bags and leave it in the jet bridge. Most of the overhead bins were empty though. This is more work for the ground staff in addition to more inconvenience for passengers waiting to get their carry-ons from the jet bridge.

Our flight was great with an unexpected upgrade. However, four days into our travel we are still without a piece of luggage. The bag tracker has not been accurate, the airline is not communicating with me or the luggage delivery service and no one is willing to take responsibility or guarantee any kind of support or reimbursement. Unfortunately, we do not have the option to easily shop to replace items as we are currently on a cruise. I have been very disappointed by United Airlines response.

HORRIBLE, my initial flight was cancelled, they made me pay $200 extra dollars and that got cancelled as well! After 6 cancellations I decided to get a refund because I needed to get home to my babies. Out of $1000+ dollars they offered me only $40 in refund! Totally unacceptable! The flight that they cancelled I was able to fly it on another airline. I had to spend $400 on one way tickets just to get home! I’m still getting the runaround.

Flight was delayed only slightly before takeoff due to traffic control. However, the flight arrived early to ORD. Good flight. United has been very reliable for me.

Overall a very poor experience - booked premium economy tickets but due to last minute flight delays , all my itinery went for a toss and had to fly economy class with no access to lounge or any compensation by united airlines to make up for the flight delays . i had expected better experience than that from united.

Onboarding - it would be great to see on the screen what group they were boarding. It was very confusing on who was boarding (even though they called it out) they were not clear and the space to board was strange.

Older plane. Food was really bad, almost not worth the effort. Huge difference with European based airlines.

Staff in first class seemed to struggle to provide service to both sections. I didn’t get breakfast though I requested it. I only got coffee after asking the opposite side flight attendant and then could never see them to request a bottle of water.

My luggage was not sent with us. Not sure if this is Envoy Air responsibility but that was a very BAD experience

American delayed the flight for a crew rest period. The delay occurred late in the evening - the earliest i can find is 10:20 pm. With a 6 am flight anyone on the flight would have already have been asleep (unless you are insane, a vampire or on drugs) and at least for me i was already on the way to the airport at 445 am the next morning when i discovered they delayed the flight until 9 am. Given the incoming flight was in the air at 6 pm the evening before this should have been figured out a lot more timely that was there only crew to use. Just frustrating given there is no consideration for customer experience anymore in flying.

Good crew and flight was on time. It’s a small plane with limited overhead luggage space. They said the overhead space was full and I had to check my bag. There was still space when I got on. Waiting for my checked luggage added 30 minutes to my trip. Not the end of the world but also not great.

Trip delayed for 2 hours because of rain. We boarded and have to get down the flight and reboard again.

No enough space plus only allowing one laggage instead of two like other airlines.

Qatar airways ,boarding arrangements at Hamid international airport could been better

Two flight changes before the scheduled flight. On the day of the flight, the flight was delayed, which caused the connecting flight to be missed. Then, I was directed to another airport (CUN) and traveled to Tulum. American gave a $12 voucher for lunch. The least expensive item on the menu at a Mexican restaurant was $9.99. Driving to Tulum was a bad auto crash, and traffic was delayed two-plus hours. The bottom line is that we should have been at the hotel at noon, but it ended up at 11:30 PM.

Miami lounges were overcrowded and we were unable to get in. We only had a short time. But the banks are too tight in all American hubs

Overall boarding and debarking is a joke. I dont even bring luggage anymore on trips because you can never allow them to be place then in the overhead bin or you have to pay or you check them which is even worse having to wait for your luggage on the tarmac.

We were bumped out of bulkhead seats we purchased a year ago. We were moved to row 5 and the folks in row 4 fully reclined making it difficult to get out to use the restroom. The seat have too little padding making them uncomfortable 3 hours into the flight. The movies did not offer closed captioning and the earbuds were poor so the entertainment was mostly unusable. The food was just passable. I would not fly Iberia/level again. Iberia also bumped us off our direct return flight so I would say the whole experience with this airline is poor.

The flight was operated by level, who had a sister’s check in procedure (2 hours) due to understaffing and a computer malfunction. While 3 agents stood at the business check in, with a total of maybe one actual customer there at a time, a huge line formed at economy check in with only 1 agent staffing the check in. Then, my luggage was lost - a guitar case with contents inside valued at 3,000 USD. The computer system of LEVEL could not locate my bag and had no record of it, and IBERIA (with whom I purchased my ticket and the checked bag) refused to help. It was a disastrous experience and I will never book Iberia again

Not bad but they lost 2 of my bags when I got to Florence

Couldn’t get boarding passes online, delayed an hour, and smallest amount of space on board I’ve ever encountered for such a long flight.

In general, I've had excellent experiences with Iberia flights and will continue to use them. In this last flight there were two things that didn't go right. I didn't get the kosher meal I had pre-requested when I had checked in on-line. Things worked out OK as we ended up eating the fish and vegetarian choices, which were really good. The other issue was that some movies for me and my wife started fine but after 8-12 minutes the content just switched to something else. The flight attendant reset our entertainment systems, but the problem persisted. We ended up choosing other movies/TV shows that did work fine.

Awful. They didn't even show concern that her connecting flight( Dallas to Mardrid) was gone/missing. I don't understand how that is even possible. Rudest answer from one of the crew was that American Airlines sold the tickets to somebody else. My daughter was not in the list.

The flight was canceled on a Thursday last minute. I lost thousands of dollars in hotels and car rental

Excellent lie flat seat for premium economy! Great staff. Bad food . Not so great entertainment. My bag didn’t make it either.

Really like the idea experience on this airline I will use again

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 flight to Frankfurt was a very pleasant experience. The food was good, but what really stood out was the cabin crew, who were exceptionally friendly, attentive, and professional. The service was excellent—honestly, better than on some much more expensive flights I’ve taken. A wonderful experience overall!

This is a very basic flight with no-frills. I just wish the seats were a little bit more comfortable.

Perfect airline, super friendly, great service, tasty food. Would fly again.

Catastrophic experience the gate selected customers were picked up to.pay 70 eur for overweight 1-2 kg. While some others were let to board without chcking their carry on bags. Unecessaey drama by Lufthansa that brings nothing just hating them by customers.

We were charged for luggage, and our ticket was with Lufthansa and was supposed to include luggage fees. So our experience was a bit bad. Also, the flight was about 45 minutes late arriving.

The flight was delayed more than 1.5 hours. Phone calls to united did not satisfy our need to get to Chicago to met family for fight to europe. I was told the flight was booked thru luftansa and united could not make adjustments. When call luftansa they were unaware of the significant delay on the united flight out of mci. They would not authorize a flight change. We went to the airport, as if we would be flying as scheduled, United checked us in, as if our flight would leave as scheduled. We took our bag to be checked to the baggage drop and the agent their confirmed our flight was significantly delayed. She worked for 30 min to get us on another flight. We ended up flying to Denver then to Munich. The rest of the family that flew to Chicago for our meet up and flight to Europe ended up flying to Munich alone. We meet up in Munich for our last leg to luxembourg. In luxembourg we learned on bag was scheduled on our delayed flight. The flight was canceled and we did not receive the bag in lux. We filed a lost back claim. Now 3 days later we STILL do not have the bag. It is apparently in luxembourg and they maybe tried to deliver, however the names on the door of the air b&b do not match the name on the baggage claim so the French speaking delivery person called no one could understand him so he took the bag and left. My brother, traveling with me under a different reservation , has been without essentials for 3 days. One or all of us has stayed "home" each day waiting on the bag. Today was my turn. Delivery window was 10:30 to 2:30. No attempt to knock or ring bell. After the hang up call, my brother called me and told me to check the door. There was nothing there. No sign of attempted delivery, no delivery man, nothing. Being unable to change clothes and having family members take turns waiting on a bag that never comes has ruined this family vacation. Thanks United/Luftansa

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.

The The check in process was terrible on both ends. It was not clear if we should use the United, Lufthansa, or Aragrant number. It took over an hour to check in on the front end – and then at return the Lufthansa online check in failed multiple times and only after two calls to their phone number could we accomplish the task. The link to the Kayak site provided no access for check in. This difficulty and ambiguity on both ends will affect our interest in using Kayak for foreign travel in the future.

You lost my bag then waiting on the phone for 30 mins for customer service just to be directed to call another number

Boarding staff, crew and food needs a lot of improvement!! It was awful Aircraft was old with minimal legspace

Our seats were reassigned on the day of departure and our small family group of 3 was split up unnecessarily — my wife was seated many rows behind myself and my daughter. The seats were also very small and very tightly packed — there was no space at all — and the seat cushions were hard and uncomfortable. I couldn’t sleep because it was painful on my butt. The cabin crew were nice and the food was decent enough, though.

Getting the boarding passes between the BA and AA apps was very clunky.

I don't know about the others but the flight attendant that took care of us had the absolute wrong approach "how do we dare asking for water or anything else for that matter"

Three major things that led to my low rating, 1. Internet wasn't available for the whole time, and 2. TV became available way into flight, after numerous system reboots, and 3. Food is not good at all.

We were never able to take this flight because our first flight from Austin to Dallas was cancelled.

It would be great to have at least two choices for a food, instead of just plain pasta 😏

Our flight from ORD was cancelled and BA rebooked is on a flight that originated before the time that they booked us on it. They did not realize we were already arrived in Chicago. Then American Airlines helped us get checked in to the new flight (the one BA assigned to us) which flight we did take although it was delayed about 2 hours, and our assigned seats that we paid for - on the original flight- were lost we did at least get to sit together. It was not too painful for all the changes and we made it to the UK alright though all in all with all the delays and cancellations the flight took about 20 hours to get us here.

though there was space in the cabin they asked us to check in our trolleys. As a result lots of things arrived damaged in Larnaca. They were fragile. When we asked the attendants why that.....they said talk to the captain!!! Unbelievable!

Horrendous, the worst ever. I would not fly with them again

Boarding ,checking in was easy and quick . Comfort was not good.
