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.

We waited in line for more than 30 minutes to go through the check in (after the staff summoned us). Once on the plane we had to wait almost two hours before takeoff. The copilot said that it was not their fault but that the plane had arrived late in the first place and lost the slot to leave again because of the heavy traffic, This is completely understandable in our times, but I would have expected a little bit of pampering from the staff. We received a tiny little cup of water because we complained. Not a coffee, not a cookie, no music on the plane, no plugs to recharge your cellphone. It was very cold inside the plane and someone asked for a blanket for a baby - very harsh answer from the staff, no blankets on this plane. I think they should review their instructions and team spirit as traveling is also the experience, not only getting from A to B. And it’s not fun to interact with staff that doesn’t seem like they are enjoying their job. And as far as I know and judging from the cost of the ticket Brussels Airlines it’s not even a low cost!

Terrible seats. Whoever designed the seats should try taking a long flight in it themselves.

Worst flight experience of my life. It was cancelled and they left us in the airport for 7 hours having no idea what to do.

Had the worst service I have experienced in 45 years of flying internationally (over 100 flights). This was an 8-hour flight and the crew was completely non-responsive to any and all requests for assistance from the 200+ passengers. My wife and I each pressed the button for assistance at least 4 separate times and no crew member ever responded. Looking down the aisle, at any given time at least a dozen passengers request-for-assistance lights were on and no crew member ever assisted any of them either. Notably, it was a very smooth flight with no turbulence, so there was no reason crew members could not provide assistance. Other than two meals - one at the beginning and one at the very end, the crew did not serve water or other drinks at all. We had to get up and walk to the end of the plane to get water ourselves. The only snacks available were saltine crackers. Crew also did not collect trash except immediately after each meal. Plane was a mess and everyone was coughing at the end due to lack of water. We found the crew hanging out in the front of the plane talking to each other and laughing amongst themselves without a care in the world about the 200 passengers. One was just enjoying a book. Don’t ever fly Royal Air Maroc if you can avoid it.

There was a technical problem with the aircraft after we boarded and we had to leave the plane and wait for two hours where we couldn’t talk to anyone. I had a connection in Toronto to Vancouver I obviously missed it. Arriving to Vancouver the flight was canceled and I wasn’t offered any another flights. I had to book one on my own charges to get back home. Also at Casablanca check in. They said our luggage will go to final destination and they did not!

Seats were very uncomfortable (tight and hard). Flight was delayed due to technical problems. Baggage took an hour to arrive to the carousel.

Not good airline doesn't understand or recognize business class customers

I love how the airline gave accommodation as a result of my nine hour layover. The service at the hotel was great.

It will be my last choice to fly this airline It was the first time to fly with them Everything extremely bad Nothing good about them Very filthy Bad service Bad food quality Bad boarding Very bad lounge. Actually it doesn’t meet the definition of lounge

Plane is dirty Food quality poor Service was not good Lounge extremely bad

There were a lot of hidden fees I paid extra for my luggage at JFK which was my leaving point and I also had to pay another extra at the Casablanca’s airport for my carry on and my backpack which is insane, when i refused to pay they threatened to call airport’s security on me. And they actually lost my luggage once I got to my destination. I seriously will not fly with this company anymore from now on and I advise you to do the same

Check in process is terrible, only one counter opens to serve over hundred passengers, agents are incompetent and took too long to get passengers boarding passes. Supervisor is no help neither. On board entertainment 90% monitors were defective.
