Spacious and clean aircraft. Good food. Economy will always be squeezed but thankfully I had an aisle seat for stretching exercises. Good selection of movies, particularly Spike Lee joint.

Unfriendly, 8 hours delayed, no lounge access even flying business. Don’t fly Brussels

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

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.

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.

The crew and the flight were excellent, the food might be better!

This was absolutely one of the worst experiences of my life. I came to Europe for a 2 week trip and the airline was probably the most disorganized airline I’ve ever seen in my life. They lost my luggage. I had tracking on it for just such an occasion and told them EXACTLY where it was in the terminal and they somehow failed to get it out on the flight that night, since we were leaving for Switzerland the next day there was no way they would get it to our hotel in time. Seriously, take another airline at any cost. It’s not worth whatever you pay…you’ll end up paying a lot more in the end. My medication is in the bag and I can’t get to it and don’t know how I will get it.

I felt the overall quality of the plane and food service was less than that of their partner airlines, United. An example was wine was served in paper cups in premium economy class. There was no real silverware, napkins or a welcome kit other than a pillow and blanket.
