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

It was really good because the employees were very nice and fun to talk to. The entertainment was nice because they had plenty of movies to watch.

Crew was enthusiastic. Meal was surprisingly good. They came to give water very frequently. Negative that the seat reclining didn't work

That was a short flight by the only time I could actually sleep

How can a national carrier and part of Lufthansa group not even provide complimentary water and a snack in such a long flight ?

The flight went well, only during the flight from Brussels to Vilnius I would have liked if they had at least given us plain water to drink.

The boarding process would have been better. When people are flying internationally and the airline is a member of Star Alliance they cannot have different rules for carryon baggage. Brussels Airlines made us adjust the weight of our carryons based on their rules even though we were flying international and our next flight was with United which does not have weight restrictions for carryons. That was just ridiculous.

Very comfortable (upgraded to business class). The audio on my screen didn’t work, but I managed to play the audio through my phone while watching the screen.

Flight was On time and landed 30 mins early considering we were flying into Newark. No complaints.

get E+, a must for 5 hours flight if you are tall

The flight was canceled the day of the flight. United says it was FAA issue, with some 35 flights canceled and more delayed.

Our flights got changed from United to Air Canada and our purchased seats did not get transferred so we had to pay for seats twice. I brought it up with Air Canada and they stated I had to go back and chase it with United. The united seats were $21 Canadian each and Air Canada were $56 each so we have paid $77 for each seat. Very unhappy

Multiple delays and not straight answer from the United team

I love United was disappointed we had a two hour delay, however the Pilot did say safety first.

I just got back from a trip with 3 flights each way. The flights were good and we were happy with out experience. There was one steward on our first flight that was harsh and grump with passengers. It did not leave a good impression. All of the other flight crews were great on the other five flights.

Food and flight attendents with positive dispositions and friendly behavior, more professional attitudes

Easy to board. Flight was super crowded though so I didn't sleep well on that cross country red-eye flight. The aisles seem ot have gotten narrower and the seat smaller whn luggage and people are getting bigger so it would be AWESOME to have more space and breathing room in general ;)

Terrible flight attendant attitude. Average 3-star hotel employee has better hospitality skills. Business class seats are literally a joke. TAP executives should ride business class in other airlines to develop some rudimentary sense of what business class is.

First, communication was terrible. The gate on our ticket was not what was reflected on the airport screens and TAP personnel were not present at either gate to answer questions. The flight was delayed and there was no announcement. Also, there was an equipment swap to a smaller airframe which affected our level of comfort. The root of all these issues was as a lack of communication. With air travel in foreign countries already being a stressful affair, lack of communication needlessly raises the level of difficulty.

Do you have a bad service And And treat customers terrible

Very pleasant flight, crew was very nice. The flight was really smooth, big plane. The seats are kind of close together, so comfort was just OK. The boarding process on the way back to New York was a little chaotic. It took a long time.There were no announcements, no loudspeaker just one staff yelling out of instructions and a lot of people crowding in before their term to board. So that could really be improved a lot.

The crew was very nice. The food was good. The entertainment on the way back to Miami wasn’t as good as the flight over. I wanted to watch Wicked but on the way over from Miami to Lisbon but the screen didn’t work. On the way from Lisbon to Miami Wicked wasn’t an option. Liked the option to check out overhead carry on with our checked luggage Overall the flights were very good. I would fly TaP again

Boarding went fast. Lisbon's gates are too small for the flights they serve.

Great pilot, textbook landing in madeira. Everything else, from booking to checkin, plane quality, seat amenities, crew engagement, and overall experience were significantly below standard. I WOULD NOT FLY TAP IF THERE IS ANY OTHER OPTION.

Worst: long walk to baggage claim Best: left on time

Got in on time. Food was the worst ever. Comfort was terrible. Check in was incredibly bad.

The flight schedules are better than some airlines. Their website is terrible, it doesn’t store any information so every time you fly you have to re-enter the data. The flight was late taking off but we still got to our destination on time.

I was very grateful for Lufthansa's role in organizing mobility support. The touchscreen on my seat was faulty: slow, stained (I couldn't get it clean), and glitchy. This made selecting movies extremely time consuming, and twice I had to start all over from the beginning.

Beautifully maintained airplane, good food, professional crew, top-notch communication. I highly recommend Lufthansa for intercontinental flights between the United States and Europe.

Lufthansa is my favorite airline and have flown oversea with them for the past 25 years: i always found them so professional and incredibly efficient from checking in to arrival. I also love their Munich or Frankfurt airports.

The United flight was excellent! The flight attendants were attentive and nice, and the food was very good! And the glasses are larger than on Lufthansa flights! I don’t want to have to ask for 15 glasses of water because their glasses are ridiculously small!

The food not that great. Did not like the fact that we could not purchase upgrade at the airport

We paid for business class, and my seat did not work at all. Each time I wanted to adjust the position, an attendant had to come to physically force the seat into its new position. They tried to fix it by fiddling with the electronics (military reset, for example), to no avail. Also, the food was just mediocre. We were at the end of a serving section, so they ran out of several choices. (This was on the flight from Los Angeles to Munich.)

The crew was the best I’ve ever encountered. Business class was spacious, immaculate, and very modern.

The plane was very clean. The bathroom was clean as well. The land crew were very polite and informative and helpful. They informed me that there is a long way and challenging to go from international terminal to national terminal and in addition to getting my suitcases and going through customs and dropping them again for my second leg of trip which was San Francisco to Los Angeles . I have left knee issue and had a recent fall with aching muscles all over, the land crew suggested wheelchair help for me, God bless her. If I did not have help, I could not make it to my last terminal. Thank you UNITED AIRLINE!

I like the service and the efficiency. I am lactose intolerant and the lactose intolerant meal in business class was not astounding. Also, the business class fully reclining seats are not that comfortable.

Food was great but they didn't clear my meal tray for 3 hours. You'd think they could check though the cabin now and then.

Better synchronizing the boarding processes. The audio announcements, the personnel and the digital signage were not saying the same thing. All confusion.

The first class seats were unusable, mine at the end of the flight, my husband's in the middle of the flight, and the one next to me was unusable either, they had to move the person to another seat.

Last minute gate change. Didn’t put our TSA global on our trip even though we asked multiple times to confirm. Did not help with food when could not eat what was served.

Our luggage didn’t arrive with us, that puts a damper on the whole trip.

The cabin was bit colder than I like but the crew members looked after us very well. They did even offer hot water bottle and hot chocolate. I cannot rate the crew enough excellent is not good enough. They really were wonderful.

Boarding is always a challenge as folks in al groups crowd around for no reason, but crew handled it well. I once again applaud the LHR ground baggage staff as they got our bags from a flight at Terminal 5A to a flight in Terminal 5C within 40 minutes...amazing!

This flight from London to Chicago was actually on an AA airline. I did book through BA but the flight was AA. Great flight, hectic in Chicago, I wouldn't choose to fly through Chicago again, but that's not the airlines fault. The flight itself was great.

Push back is not working when I complaint a male staff he told me that most of the seats are like that so we can’t do anything

Seats were way too small. I got claustrophobic waiting for trash from meal to be taken away. I couldn't move to even close my tray until trash was taken.

Was 3 hrs delayed and my poor friend I met in Barcelona was waiting at airport for 3 hrs. Dallas airport was awful
