It was good until there was a 3 hour delay because there was not any pilots to fly the plane.

Boarding was chaotic. I didn’t finish dinner because I went to bed early. Breakfast omelet was overcooked and tasteless but croissant was better than usual. Plane was dirty—crumbs in every seam and lavatory was poorly maintained (paint peeling, etc.) and toilet paper had not been refreshed before takeoff. No cubby for storage in first and seat was narrow.

Wifi wasn’t working well so we couldn't view any media.

Food service was bare-bone. Better bot to have any at all rather than hand out premade coffees and cookies to random few passengers.

Crew was great. Friendly, calm, interesting, happy to be there. That makes a huge difference. Plane was very quiet. Also quite empty so I had three seats to sleep across

Had assistance at airport getting from arrivals gate to departure gate; I couldn't have managed without that extra help. Thank you Delta.

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

More space in the cabin. The guy in front of me leaned his seat back and I felt he was sitting in my lap.

Was a great smooth flight from Detroit to San Diego.

Late flight, always blaming the flight crew, stale almonds, pushy people. Why don’t they have the people sitting in the back board first? So much easier getting through an empty plane! Duh!!

Quick and efficient as always. Air France managed to loose and damage my luggage that never made it onto my KLM flight.

The food from Lagos to Amsterdam was was very poor compared to AMS-YYZ

no issues at all... Kudos to the food. This time was really really good

The food was ok. The crew seemed like they were cranky. I had one guy get mad at me for passing in between the storage area to get to the other toilet. I can understand if it's not allowed but reprimanding me like I'm a student saying "This is the last time!" was not appropriate. During my meal time, there was a French family around me. No problems there but when we usually have meals, they are supposed to put their chair in the upright position. These people did not do it and the steward did not tell them to raise their seat in the upright position. However, I was told to do so! So, me and another person next to me had to eat with the monitor almost touching our faces. Furthermore, a lady in front of me was putting her feet up and preventing another elder passenger from putting her seat back. To make it worse, she was continuously hitting her back into her seat, shaking my monitor while I was watching a movie. A crew member did speak to her about it but then she accused me of pushing her seat forward! The crew member gave me a death stare and told me to stop pushing the seat forward. I did not even touch her seat at all, if I did, she would know it. Her boyfriend also stood up and tried to push her seat even further past the maximum decline to no avail. None of these people were reprimanded but the steward, some bald guy, was extremely friendly with them and did not even try to instruct them to do anything until it was time to land. I resisted the urge to really argue with them because I would have obviously been seen as the aggressor (I have no idea why). I hardly said anything on this flight except "more wine please" and "sorry" if I bumped into someone accidentally. Overall, it was an annoying flight and I had to resist the urge to yell at the steward and the people he was overly friendly with. The happiest moment of this flight was leaving it.

Overall a good experience. We were disappointed when we had to check our carry on due to the plane being full. KLM hadn’t notified us and we had valuable items in the carry on but they still made us check it. Some of the food was great and some was mediocre. Crew is really kind and funny.

One of the vstewardeses wanted to bump me of the plane for absolutely nothing. There is CCTV in the plane ans everything can be verified. Very disappointing , you all will see, o other 5 years and the passangers who does not smile to flight attendent will be bumped off...

I travel frequently. The flight was late again... KLM should really try and be on time

The plane was clean and the staff was friendly. Food and drinks as expected on international flights. The entertainment system was old style, with a pullout controller, and selections not as extensive as on other flights.

The boarding was one of the worst I’ve ever experienced. The fault lays on Ohare Airport and not so much the airline. The waiting area by the gate was the size to accommodate a regional flight for 20-30 people and right next to a busy walkway. When you cramped nearly 300 passengers into that space is was unbearable.

All and all pretty good. It’s crowded but that is what flying is all about. But no complaints otherwise.

After the morning frenzy of 35 min wait through CLT security at 4;30 AM, it was nice to have a smooth pleasant boarding experience. This 6:30 AM flight was not full. We were able to get seated swiftly and took off promptly. Nice touch they distributed the old fashioned headsets with 8 mm jacks. Snacks were decent and arrival was uneventful.

My window shade didn’t work. So I missed coming into my city. ☹️

Flight was delayed in the gate by 5 hours and ultimately cancelled- rebooking service by United agents was terrible

Everything was pretty good except for food. They need to improve on it compared to other airlines.

Flight was delayed due to the late arrival of the catering truck, which is quite unacceptable. There was a beverage service, but no pretzel, or cookie, or nuts were served in coach.

Not worth the premium paid for the first class ticket

Not worth the price of premium class ticket paid, felt more like steerage.

Flighty delayed on boarding - then group 1 had to check their carry on bags but groups 3 and beyond could carry bags on - very inconvenient for weekend business trip with no checked baggage. Then delayed on the runway - before take off. No communication from pilot on why or how long. Wifi/Entertainment didn't work for 4+ flight. Upon arrival, attendants announced wrong carousel for baggage claim - everyone was waiting at the wrong place for their checked bags. This was a mess united!

I flew Delta last week and United Airlines is a poor substitute mechanical problems with the plane and shitty food among other things made my travel experience what’s become to be expected from United no way is it ever worth the money they make us pay

I had a great flight. Everything went smoothly and the flight arrived early.

For such a long flight they should offer tea or coffee in between two meals.

No seat assignment . Last on board . Though I would not receive any boarding pass

last minute was rebooked. This rebooking made me miss my connection, added a stop in my itinerary without my approval, and had me arriving 10 hours later to my destination...for a delay that was 2 hours. To boot, my final flight from London to Athens booked me in a middle seat, where I originally booked all aisle seats. This was incredibly uncomfortable for a 24 hour journey and made me incredibly upset.

Did not appreciate “hidden fees” to check a bag for international flight and purchase a seat to be next to my spouse. Won’t choose this airline again.

The flight left over 2 hours late and caused me to miss my connecting flight. Consequently, I missed my cruise ship out of Barcelona. The cost associated with this miss was as follows: Airfare to Sicily Italy to get on the ship TWO days late - $232.30 Taxi from Airport to hotel $35 Dinner at hotel $38 Hotel in Barcelona - $208 Taxi from Sicily to hotel $70 Hotel in Sicily - $148 Prorated time missed on cruise $ 1,143

No meal. Flight crew was wonderful, happily finding me storage for my guitar. THANK YOU!!!

My seat was moved multiple times. I picked out the perfect seats beforehand. I even paid extra money for them. However, I was moved to a middle seat without warning at the last minute. It was like my worst nightmare. But other than that, the actual flight was good. Everything was on time or even early and the flight was smooth.

A220 plane had 5 seats across which is great for couples who can snag the A&C seats. Seat itself is borderline comfortable but still tough on a 5+ hour flight. Overhead bins are small so if you're not in at least boarding group 5, you could be in trouble. No included food service. Non-alcoholic drinks are free but even the most basic snacks are for a charge. Price was reasonable for the only direct SEA-YUL flight. Boarding is efficient even managing passport checks. Worth flying for the direct flight.

The original flight from Boston to Toronto was canceled because of a mechanical failure. I was then scheduled on a flight to go from Boston to Montreal and then Montreal to Toronto. The flight was extremely full and I had to check my carry-on bag. When I actually got on the plane there appeared to be room for my bag. I understand the mechanical failures happen. But it was frustrating that they pestered me to check my bag when I don't believe it was necessary. Additionally, not just with Air Canada, modern airline seats are incredibly uncomfortable. There is considerable research that shows that the shape of them is poor for back health.

Unable to initiate refund/reschedule the ticket #worst experience #lost 900$

Economy class has no legroom so if you have the money worth to upgrade! Food was absolutely horrible! The crew was super nice!!!!!

The flight was provided by Aer Lingus and our seats were in a poor condition (15A & 15C). They looked like they needed repairing/replacing and were uncomfortable for such a long flight. Also the arm rests on Aer Lingus planes do not lift more than around 45 degrees, instead of the usual 90 degrees upright, meaning you cannot maximum the space between you & your travel companion so as to be more comfortable for such a long flight.

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. Delay, lost vacation time and travel time now more than 24h

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

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

Very bed boarding, there was overbooked and make a lot of problems and noises

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

On my way from Chicago to London, I was seated next to a quite heavy passenger. I could barely move. BA should have ensured that overweight customers are placed in comfortable seats and not to penalize also other passengers because BA is not willing to accommodate these passengers and their needs. No respect at all.

The flight as far as timings go was excellent. Unfortunately we ended up sat with someone on a night flight who had been drinking alcohol before boarding and BA staff were happily serving him more alcohol. He was very drunk which made our flight uncomfortable and awkward. My partner had this person lying on him whilst asleep. Alcohol should be served minimally. If there had been an emergency this person would not have been in a fit state to act accordingly.
