great starting with the business Class that's was Amazing . thank you United Airlines and brussels Airlines

What would be infinitely better if for Kayak to not offer this flight as if it was completely different airlines rather than United and then filtering me through some creepy discount site.

Everything works smoothly once I got to Brussels. Flying with United Airlines from Atlanta to Chicago and Leaving Chicago for Brussels was a nightmare though. Slept at the airport in Chicago because my flight got delayed from Atlanta to Chicago. No accommodation provided because united airlines said I had economy ticket.

In general, flight attendants were not very welcoming. Because of delays in departure and luggage handling, we missed our connecting flight. Offered a later flight on standby but available seats were then taken by 4 or 5 airline crew so slept at airport and got home next day. I am a frequent traveler, and this experience was the worst.

The flight was excellent. The crew was great. The food offerings were very good.

Liked the excellent United crew, the food selection, the comfortable cabin and the excellent movie and tv shows selection. The interface on the screen is also excellent and gives the option to let the crew know to wake you up for meals, or not. I disliked the onboarding experience at the Brussels airport. The process is convoluted and was not explained to any passengers. I also don't understand why thee is an additional security screening when getting off the plane from Africa, when there was none when getting off the plane from the US.

Worst and most inattentive in-flight service I've ever had.

The 787 Dreamliner was probably the smoothest aircraft I have ever flown on. Made for a lovely trip

It was a good flight. The entertainment could be better.

The travel on premium economy class was very positive. Comfortable with plenty of space and leg room. The service throughout was top notch. Crew members were kind and helpful. Food and entertainment were excellent.

Long line with check in at the DIA British Airway counter.

It was great overall. A few slight improvements could be made on the onboarding process at the Gates with announcements and clarity of communications (both at the gate and in flight). The movies in the entertainment options could be improved for bollywood, hollywood.

Everything excellent except for bag drop off. We started at the D area and that was so slow that it was eventually closed just as we were about to go to a station. We then went to F. We got one suitcase checked and then the screen showed that the station was no longer operable. There were long lines everywhere so we had to ask if we could butt in to the next station to finish. Again, this was the only incident, otherwise it was an excellent flying experience

There were no gluten-free vegan options available, so food was very limited on this flight, and some of the crew weren’t especially helpful about it. To make matters worse, a passenger was sick on board, and although the area was cleaned, the smell lingered for the rest of the journey. On top of that, we ended up circling for an extra hour, which only made the unpleasant situation drag on even longer.

We never made it onto this flight due to BA's lackluster organisation.

I have nothing but amazing things to say about every staff member I encounter on my transport from Brussels (Bru) to New York (jfk) via London (lhr) after many flight delays and changes every colleague I asked for help gave me the utmost respect and did everything in their power to make sure I arrived in Washington DC to make it in time for my brothers wedding. The flight attendants on the flight from Bru to lhr move me to the front of the plane so I could get off quickly and try to make it to my connection to dc, when I missed that wagans at the support desk did everything in his power to get me to dc via two transfers. Especially during the busy holiday season I am so so grateful for the amazing customer service that I encountered today.

Firing with British airways leaves me feeling stressed and disappointed. They are substandard in so many aspects of airline travel.

Worst trans-Atlantic flight in years! The seats were incredibly tight, both in width and depth. The back selection was so cold, it was like traveling in a refrigerator. Although I had an entire row, the seat arms would not go up, so I could not take advantage of it to sleep. However, the crew was smiling and helpful and really seemed to enjoy their jobs. The food was the worst I have ever experienced on any flight. The PA system blasts announcements to the point of hurting my ears when using the audiovisual equipment. Not safe or sat. Also, I did not like the bait and switch tactic. I put in a search with one bag and the other flights had put that into their price, but BA did not and made me pay extra for it which would have made the price comparable to others. Also, even at check in there was no “choice” of seat, unless you paid extra for it even in the same row. No other airline I have been on does this. Once check in begins, normally, you can choose any unoccupied seat in your category. These tactics and the lack of comfort means I will never fly BA again.

An early flight and a bit confusing where to check in with British Airways; good we asked at the information counter the night before as we stayed overnight at the Sheraton on the departure level.
