The flight itself was fine, food was expired and gross, staff were mostly amazing! KLM messed up rebooking for our first two flights that got cancelled and we almost didn’t make it to Amsterdam for an additional two days

The flight itself was fine, food was expired and gross, staff were mostly amazing! KLM messed up rebooking for our first two flights that got cancelled and we almost didn’t make it to Amsterdam for an additional two days

I think I previously submitted my feedback about flight lead Katherine in a different field by mistake. Please see those comments. Comments for Hyd to AMS are it was good. The flight lead and service met expectations for satisfactory high quality service but the flight lead did not stand out as exceptional as did the leads on the other two flights so I don’t remember anything specific one way or the other besides the fact I was satisfied.

Flight lead was a gentleman with silver hair and he went out of his way to shake hands and interact with each passenger seated in business class. A medical emergency took place during our flight and he handled it with perfect poise and professionalism. He was gracious and confidently competent. Just what you want from a leader,

Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional

Seats were nice and comfy. Crew was polite and attentive. Business class is awesome and worth the money.

It was operated by Delta. Boarding took a long time. How difficult can it be? Overall decent trip. Liked the Salt Lake City airport. Better option than Chicago for transfers.

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

Nothing, it was a fraudulent transaction. You probably should have caught that.

Flight was 2.5 late. Maybe not United’s fault but late none the less. We were late as well on the first leg. WiFi quit working with an hour left.

Flight staff and all was fine. Food always sucks on planes so nothing new.

Wonderful flight! The crew was good, check-in was good and orderly and the flight was uneventful and good.

The international portion was good. Food and beverage options were good. The sustainable wooden eatery was less than desirable. Your Star Alliance partner ANA provided real silverware. I'm 6'3" & 198 lbs and felt cramped in the exit row. How can that be? Flight attendant all had a pleasant disposition which is always good.

The staff were polite and professional. I found the boarding for First Class Business customers not great. They didn't offer me pre- boarding. Just regular zone 1 boarding which didn't feel great. On board and throughout all of our United Flights we found the staff wonderful. We'll definitely fly United again.

Boarded from a very small gate at LAX. Staff at gate had us line up, then waited 25 minutes to board without a word of explanation. Plane arrived on time then waited 20 minutes for a plane to vacate our gate. Majority of bags arrived after 15 minutes but it took an hour for a small number of remaining bags to be off-loaded despite my “priority” bag tag.

The boarding process on the departure from LA was rather slow even though I was in Group 1. For first class, I was not expecting to have to pay for Wi-fi but I did and then the wi-fi was spotty. The entree was surprisingly good and so that was a pleasant surprise. However, once I got to Houston, it was terrible. Unfortunately there was bad weather but the constant gate changes for my connecting flight was difficult to manage due to having to navigate back and forth between different terminals.

The pilot had to extend the flight time from san antonio to Houston to burn off fuel. This caused a lot of unnecessary stress since we had a tight connection to Aruba. And with no other flights going to Aruba we were worried about spending a night in Houston. We had to to run to our connection because of the flight crews mistake. Not happy.

The flight was delayed, they didn’t even have water for the toilets or for drinks

Flight was good, little delayed because of busy plane traffic

The boarding process, airplane, entertainment, beverages and crew were very good. But the food left a lot to be desired, especially for business class. I had a chicken breast that was tough and rubbery, with little flavor. It wasn't even up to the proverbial "banquet chicken" standards. Very disappointing. There was only one offering of bread, OK, not a huge deal, but it's a nice touch to be offered more. Similarly, other airlines' crews come by to offer more drinks, though the crew responded when asked. Good flight overall, but the food just wasn't up to the standards you'd expect.

The plane was very creaky and lots of ringing. Plane was dirty and dingy. I couldn't hear the captain's announcements from the flight deck. Not sure if it was the captain or the audio equipment, but good thing there wasn't an emergency where we needed clear instructions. The overhead compartments were clearly full, but the flight crew allowed people to stand in the back with their carry on luggage. Then after everyone boarded, they had to go to the front to gate check their luggage because there was no room for their bags and then they returned to their seats...such a waste of time when clearly the overhead compartments were full when they originally boarded.

I booked an aisle seat and was given a middle. At 6'4" 230lbs, it is not ideal to fly in the middle row for myself and passengers.

Canceled flight for unknown reason after numerous delays and only available flight was the following day yet no compensation. No weather problem. Then had to fill out form to get refund. American used to be a quality airline - no more, very sad!

Awful. We had an 8 hour mechanical delay- no vouchers and no kind/courtesy/professional representatives in the entire airport. Not only was it a terrible experience for both my 7 year old and myself, I still have not heard back from American about how they’re going to correct it- I’ve sent 2 or 3 emails about our experience- which was just awful. Not to mention according to national traveling laws, we should be reimbursed… but of course they’re not responding.

entertainment choice was excellent for both movies and audio. Food was quite good. Staff was excellent and flight was on time and smooth.

Overall it was good but not great. The aircraft was an old and seats didn’t recline in business class unless you kept playing around with it.

The plane was subbed for another last minute, the gate was changed last minute. Could live with that but we boarded and there was a delay which totaled an hour in the end. There was a technical issue which meant wheels needed to remain out for ten mins after take off. My USB phone charger was broken as was the headphone jack which meant I could t enjoy the IFE and could use my phone after a few hours. Even the map function on the plane failed to work after a few hours.

The flight was delayed and we were told the airplane is on its way to the gate from the hangar. We were told this for 2 hours and the flight was continually delayed in ~30 minute increments. Then we ended up having a new airplane. The issue wasn’t clearly communicated and it left everyone feeling confused about when we would actually be leaving. Whenever they communicated a new boarding time it felt arbitrary and random. The boarding process was a mess and disorganized, which made it last longer than necessary. Landing was rough. Seats were uncomfortable.

We missed our connecting flight in Frankfurt do to security and all hell ensued then.we got rebooked to Washington got there round 10 am ish didn't find out till 630 we were rerouted to United!! Then we started getting updates

I like crew. They are friendly. The flight was delayed to take off for 1hr and that caused panic at Houston Airport to catch connecting flight due to security check delay. If it has reached on time I would have sufficient time in collecting bags and security check

I hated the FRA Airport. Confusing signage, including the path to Immigration and Security It seems that the airport grew haphazardly over the years. I have been through multiple WW Hubs with much better experiences.

Great experience. Flight was on time and reached destination on time

Upon arriving at IAH, it was informed that the luggage had not arrived. Still waiting to hear back when it will be delivered.

I had handicap and pre board due to a recent broken arm, was made to find my own help placing carry on baggage in the storage above. My tv and entertainment unit did not work correctly, requested help and it took 30 minutes to get help, she did not fix it or come back to see if it was fixed. I went to her a second time and she did another reset, still did not fix.

Did not fly to Houston as original flight was cancelled.

Two things to note here. First, Lufthansa separated me from my small children. Apparently you need to pay extra to ensure that your children are not abandoned. This is different from KLM-Air France, where children sit with their parents automatically, and I usually fly KLM-Air France. I didn't realize Lufthansa was different on this score and is willing to leverage the wellbeing of small children to generate more revenue. Second, my flight arrived 3 hours and 54 minutes late, so I am entitled to financial compensation as per EU passenger rights regulation. From other aspects of Lufthansa's behavior during this trip, I expect that their approach to this is to start a war of attrition with their passengers to avoid giving compensation as much as possible - again, very differently from KLM-Air France. But we'll see, maybe I'll be pleasantly surprised.

The plane boarded 5 hours late. This made for a very long travel experience - 3.5 hours for getting to/taking the connecting flight (Air Dolomiti), 5.5 hours layover in Munich, 11.5 hour flight to Houston, 1 hour ride home. After landing at BUSH airport we spent 30 minutes on the tarmac waiting for United staff to prepare the jetway. Flight attendant admonished my wife for briefly opening the window shade midflight to take a look outside.

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.

Had a plane! Have a plan! Have my luggage! 10 hours of travel turned into 50 hours. Good Lord!

The first leg of our booked flight was severely delayed, and by the time I could get to an agent to see about re-booking, it was impossible to arrive in time to board for the final leg to Reykjavik. We were flown by American Airlines to Heathrow but didn't arrive in time to take the British Airways flight. BA only flies once a day to Reykjavik, so we had to purchase an absurdly expensive flight through Icelandair out of Gatwick to arrive in time for an excursion that started at 9 a.m. the next day. Our luggage got lost in the meantime and wasn't found for several days.

God food! Although some of the snacks were not to my taste. Nice amenities in premium economy made for a comfortable flight. The pilot was able to make up about half the time we were delayed in the ground (we were delayed over an hour before takeoff due to a shortage of tugs) Nice movie selection for entertainment. We were last to board the second leg of our flight due to.complications during transfer from the first flight of our trip, but did manage to board in time. We really enjoyed the video presentation for flight safety. Hilarious gets your attention! Really nice, sufficient accommodations for overhead storage, didn't seem crowded or jam packed. I enjoyed being able to track the flight on my monitor. I was disappointed that there wasn't free WiFi during the flight, I thought that was a complimentary service but you had to pay extra. It felt like we were nickled and dimed on that one.

Very comfortable flight and simple and directed one way and back. Amazing price.

24 hour delays aren’t even heard in 3rd world countries with archaic transportation systems. I’m never flying American Airlines again.

I was attacked in the Miami airport and the staff did nothing. On my flight from London to Miami one of the flight attendants screamed at me and demanded I keep my seat in the upright position at all times during the fight so the man behind me was comfortable for the flight. I will never in my life use British airways again

There might be more food options for people who can't eat so much starch/sugar/bread/rice. Meat, cheese, walnuts/pecans for snack, maybe jerky or other kinds of meat-based snacks would be better than bread and rice and sweets. I had an extra chardonnay, which was fine. The entertainment was great.

They cancelled our flight the morning of departure at 4:30am.

The staff were very friendly and helpful. The seat configuration was as awful which meant no one had any privacy. The food was very good.

We flew business class. The staff was polite and responsive. The accommodations were comfortable and spacious. The area was clean.
