Landing was a little hard. Food was not great My prior review was for the flight to nyc too

Landing was a little hard. Food was not great. No options.

Five star experience all around except for my seat, which was broken. It would only go down 70%.Of the way. It defeats the purpose of buying a business class ticket if you don’t actually get to lay flat..

I love this airline.God bless CAO and the whole staff of this company

Great staff, efficient and knowledgeable. Very helpful with others and considerate towards those with children

WiFi would have been nice and some more powerful usb ports, available ports could not keep my phone’s charge much less charge the phone.

Not so good. I paid for a preference economic seat, and I couldn’t incline it back because it was blocked. They explained me that because is the last before emergency exit. The company new that but it was not explained in the seat selection

It was on time. Snacks could have been provided for free.

Tirana was crazy check in and getting bussed to another gate. Both Germany stops were intensive customs but organized, but that wasn't the airlines problem. The crews were fabulous on the planes. The announcements were not easy to understand in English, slurred speech. Customs inthe US were fast. We waited for luggage, three later arriving planes had their luggage and left before us

Business class old style from 10 years ago. Ok for short flights but nor for 12 hours journey. The passenger near the window have to jump over the passenger seat aisle side or wake him up to upright the seat. That’s not the business class that you expect on long night flight. Seats are not so confortable. And believe it or not no wifi!

I never board the flight. My visa was delayed and when I tried calling Kayak, no one answer and I still have not heard from anyone.

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.

It's not the staff's fault. The cabin crew do their best but the setup in Stansted Airport by Ryanair is poor. The herding of people like cattle is unacceptable before boarding and is something that's in every airport but only in Stansted have I seen the queueing of passengers outside the plane on the tarmac and the crew only turning up with maybe 5 minutes to depart. This is a resource issue . Yes prices are good but seemingly comes with a price of poor treatment of customers. I'll pay more next time

On time arrival but the aircraft had seen better days and needed a deep clean.

Flight was fine, crew were good, cabin director spoke far too much; disembarking at Dublin Airport and entry into the terminal building was just dreadful, like entering the back door of a neglected factory building. What an awful impression it must give to first time visitors to Ireland.

Flight was over an hour late. Boarding was really messy with long queues at the plane.

Cabin crew couldn’t be less interested. Cabin manager was the most arrogant and the rudest I’ve encountered in many years.

Good but both flights were delayed by nearly one hour making boarding tedious. We had to wait with no information

The flight arrived within 15 minutes of schedule. We hate the cattle-like boarding process seen often in Europe. After your boarding pass is checked by the airline staff, you wait standing up in an area with no seating for several minutes.

Big delay on run way not much explanation why, missed a important meeting in Dublin, maybe if they did nt persist measuring everyone bag over 2 cm we would have got off on time.

Their customer service needs an overhaul. I wish we could access them and the could be more helpful. Also, the website has been crashing and I had numerous technical errors. My flight was cancelled and we spent so much time trying to get help because the tech was failing.

The punctuality of f the flight was super: we left on time and arrived about 20 minutes early - and the cabin crew were both friendly and efficient. The only downside was that Ryanair appears to have resumes its old obsession with sizing cabin bags again after a long and welcome absence.
