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.

Boarding was delayed and we had to get on buses to plane so group # didn't matter. No food or drinks served gratis. Seats were small, knees smashed into the seat ahead, didn't recline. Crew was excellent though.

The flight from Seattle was delayed, which made me miss my connection to Florence. I was re-booked NINE HOURS LATER!!! That’s basically a vacation day lost. British Airways needs to partner with other airlines when possible to get a more realistic travel time, if delays occur. I realize there aren’t many flights to Florence from London, so I would book differently were I to return. The actual flight from Seattle was very comfortable and the crew was great, no faults there. I enjoy British Airways, this was an anomaly.

Our original booking with Kayak -our first experience -was exactly what we wanted and worked well. Updates were friendly and reassuring as were the contacts with UnderPricer so a big win-win. We learned a lot on your reliability and will definitely put you on our organisational list for the future.

The crew could not have been more helpful, my meal was excellent, I slept peacefully until right before landing, and the BA lounge was a godsend. The only negative I encountered was the coffee both on the plane and in the lounge. Not to my taste but that’s a personal preference.

Plane and seats ok. Dinners going and coming back were not fantastic. Breakfast from Seattle to London fine with bagel, cheese and fried egg. Second meal on London to Seattle not my favorite of kind of pizza sauce in a pastry. Came with water about three different times on each of my long flights. Staff on all very friendly and helpful.

I don’t understand why a reputable airline like BA would delegate their London flights to AA. Makes no sense to me, as most domestic carriers do such a poor job these days. Terminal 3 at LHR is a total dump

We ordered kids meals - which were not kid friendly at all! (the breakfast that is - scrambled eggs on a bed of spinach and asparagus?)

Uncomfortable seats. Crazy seat assignments separating families when they could easily have put them together. Good communication from pilot about arrival time after delay in departure. Toilet ran out of water in sink. Snack box poor for flight of this length.

The bed in Club class was not very comfortable, everything else was good.

Cancelled flight minutes before boarding. Rescheduled flight was two days later
