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.

I wish there were outlets to charge my iPhone. The crew was great; we had a female pilot who was great with explaining what was happening and delays,

It was good, although we could not get our preferred seats, we did enjoy the whole experience from Costa Rica. I still don't understand why our luggage is not the first to come out at the band.

Great flight. On time boarding. Smooth flight and on time arrival at EWR. The flight crew was marvelous and there was a great selection of movies on the entertainment system. Our bags were at the carousel before we got there. Another excellent flight from United.

Very turbulent trip made it pretty bearable, plus the lack of refreshments served and the lack of any air conditioning before takeoff which took an hour or more.

For an expensive flight to another country, United has a lot of nerve serving pretzels and no meals (unless, of course, you want to buy something to eat). Unacceptable.

They brought an empty plane to the gate. Then a flight delay was announced for maintenance and waiting on a part. I was then put on a flight to San Francisco instead with a connecting flight to my final destination. Arrived at my final destination 2 hours late.

Flight team stood out for perzonal attention, kindness at bright cheery attitudes at 8am. Very helpful.

Quick and seamless boarding. No entertainment but fast Starlink wifi for this short trip and the staff was really friendly.

We boarded late. The crew at the airport was dismissive. The seat cushion on the plane was uncomfortable.

Flight from London was delayed so missed the connecting flight. Taking 2 days to get to destination which should have only taken a few hours.

Too cramped up for the better seats I paid for.

I didn’t like my seat in my return flight from Montreal to Orlando at all; considering I paid extra for better seats. That middle seat was cramped up way too much.

Suitcase didn’t arrive to Stockholm. Chairs y comfy and not even water is offered

Bad baggage and people management at boarding forcing me to dispatch my bad despite being the perfect size and respecting everything perfectly, whereas many did not and many free empty spots on the plane as usual… making me loose time and my planned bus at arrival to go to Geneva. Costing me 100 euros extra! So Brussels airlines needs to refund me

I never board the flight. My visa was delayed and when I tried calling Kayak, no one answer and I still have not heard from anyone.

All great. Very efficient. Good emails that kept us in the know

Original flight was canceled, booked another one and find out when checking I was on the waiting list. Horrible experience

Actually this is my first time using airline I was in every single thing that happened throughout our journey, the appearance of the plane inside furnished about the seating the flight attendants and many many more I was so excited throughout thank you Brussels Airlines for the great service.

On board service was decent. I like the legroom at UA that seems to be more than in other airlines

this flight was awful from pre-boarding to on the plane. There needs to be more coordination between TAP and My Way. We were in first class and I am handicapped. BY the time we got on the plane there was no place for our baggage and the crew did not handle the situation well. They gave us an argument and said that we'd have to have it checked. Then, after I complained they moved some people's bags to put our small carry ons several seats back of our seats which were in Row 4.

Bad. They gave me a voucher for food to use at the airport but didn’t have time since I had to catch the other plane. No refunds and lack of communication

Negative. Food was awful, seat broken, flight was late, baggage lost and damaged

The ground staff did not load my bag onto the plane and despite me watching from the bus that my bag is not being loaded and taken back on the cart to the terminal, I pointed out to the staff and ge laughed upon checking my tag and knowing they made a mistake. Instead of calling the cart back and loading it he said we can’t fo anything and you should file a report upon landing at RAK. I told them my stay there is short and i needed my bag as it had everything I needed but no avail. Even the pilot was informed, staff of the plane was aware but all in don’t care mode. Upon arriving at Marrakech RAK, i filed a report and being told it might come in next flight tomorrow and we don’t provide delivery service, you must come and pick it up. If it doesn’t arrive on time then it will be sent to your home in the US. Unbelievable stress and inconvenience that could have been easily prevented by the ground staff.

The cabin crew were curt, not with me, but observed with other passengers. They were unduly rude and it was unprovoked and when they realized they were wrong, they made no attempt to apologize for their own confusion.

I was disappointed of the crew, not friendly and attentive. Delay one way for fuel leakage and the plane is so hot. Not that great all around but I’m glad I experienced it so now know better.

Flew Business class and did not like anything, flight attendants were rude and not helpful. Food was of poor quality and I did not eat meals.

Wonderful just hope the had more direct flights to Boston

Boarding process was fast and efficient. Short flight but on time and well organized. I would certainly fly TAP again.

Very long line at the gate, moved slowly. I had expected that boarding a flagship A330neo would be with a jetway directly at the gate, and not a long bus ride to the airplane.

Not great - seats were very narrow and food was terrible.

Some of the crew was sassy and not super helpful. The food was okay, but it seems like they were all unprepared compared to my flight I did from JFK to Frankfurt

We missed our flight. There was not enough time built into the layover to get through immigration, customs, bagclaim, bag rechecking, and the long trip to another terminal and gate. Kayak really screwed up. We took the bus up to Wisconsin and then were picked up in Brookfield by private car. It was lucky we didnt miss the last bus out.

We were in premium economy seats that appeared to be locked in plae, No reclining. My aching back.

I don’t understand how they charge as much as they do for such a poor experience

Lufthansa flight LH04414 from Munich to Washington DC, was fine. Efficient and safe!

This review is based on 2 things: 1. The lack of hygiene on the plane. 2. William - the head flight attendant. The lack of cleanliness on the plane upon arrival was appalling. Being given a sanitizing wipe upon boarding of the plane is shocking when you consider the cost of a business class flight. UA expects me to do their job and clean all the bread, food and debris left from previous guests. Does this sound normal to you. The seat, the food table and the sides were full of crumbs, chocolate and dirt. When I told the flight attendant they just gave me more wipes so I could clean it myself. Secondly, William the business cabin head flight attendant was so busy flirting with a couple in the front that his attention to the other guests was minimal. He continuously asked them if they were ok or if they needed anything and it didn’t matter if the rest of us needed anything. And if you are the lead attendant shouldn’t you be checking if the bathrooms in business class are clean and needing toilet paper. There were 2 bathrooms in business. Halfway through the flight the first bathroom was closed and the second bathroom was dirty and had no toilet paper one hour and a half before the flight landed. He needs additional training on prioritizing things. He should care less about flirting and more about his work

Crew was outstanding, helpful and friendly. Food is deteriorating. The snack at the end of the flight was not good, a greasy moosh of toast cheese snd other unidentifiable ingredients. Coming from Germany a pretzl with butter would have been better. Entertainment had a great selection.

Give yourself over 2+ hours layover because if flight is slighlty delayed and you miss your connection, Lufthansa will do nothing for you

United lost my travel information and canceled my original flight. I had a seat assignment but was refused the booking. I had to prove that I went to Germany on United Very concerned about security that no one recorded my passport from Cleveland to NY and NY to Frankfurt I arrived at home at 12:30am on Saturday instead of 8pm I expect a full refund from United Please provide information to assure compensation
