Klm start boarding while somw air issue in the plan

I appreciate that KLM was proactive in informing me of the 2 hour delay which enabled me to replan my travel. It was a bit stressful not knowing whether my connection from Montreal to Ottawa was happening. But the ground and air crew did a good job at comforting and assuring me.

Cabin crew professional, polite and friendly, boarding was seemless, but come on KLM surely you can do better than a pack of cheesy biscuits as an inflight snack

Cabin crew were excellent, very proffesional, polite and friendly, in flight snack was underwhelming, a packet of cheese biscuits, im sure KLM could run to a sandwich!

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

This portion of the flight was through Indigo. A local carrier. So all economy seating. No real service some refreshments for purchase standard economy stuff.

Transfer at Amsterdam airport is very convenient and the airport is easy to navigate. Boarding was also quick and easy. Cabin crew were excellent and the meals were good, although lacking in options.

Overall very positive. Boarding was quick and organized. Cabin was clean and seats were reasonably comfortable. Cabin crew was excellent and the meals provided were also of good quality

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional

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.

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.

Crazy long boarding times, messy, inexperienced, overworked, and visibly tired crew, very uncomfortable seats and no compensation for delays.

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

I couldn’t understand the aircraft tannoy announcements I was in seat 20C - nobody in our row could either. Speakers a bit too quiet plus messages read out too fast. Otherwise excellent flight. (Flight delayed by 50 mins)

Unnecessarily delayed and remarkably inefficient boarding contributed to a significantly delayed departure. Seats/legroom astonishingly uncomfortable even by Ryanair standards (minimal legroom plus reinforced plastic seat backs ensure you get punched hard in the knees every time the person in front moves, and as a 6-foot passenger I had nowhere else to put my legs. Upon late arrival at the gate in Luton we were kept waiting another 20 minutes before being allowed off the plane. Both Easyjet and Wizzair are currently a better bet.

Awful as usual the air stewardess loved her own voice and would not stop talking on coms for 2hrs please please please shut up I can’t hear my headphones and don’t want to buy juty free

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.

The lady at the boarding gate was so rude. She was challenging people being in priority and looking them up and down as if they weren’t dressed for first class. This was Ryan air priority. We all sit in the same seats. She loudly called out to embarrass a man who she believed had cheated and got in the priority line. He had a valid priority ticket and even worked for Ryanair. Also challenging visas insisting people download them until they proved on the government website it wasn’t required to print. The Ryanair employee who was challenged said she is always like this. She also pulled people from regular boarding as they were fashionably dressed and upgraded them to priority and changed their seats. That was comical. I think she felt she should be working for Emirates first class, although they would t have stood for her rude behaviour

On time boarding, on time departure and early arrival. As it should be. Yes, the comfort and benefits are very poor, but therefore the ticket is 6 times cheaper than with a flag carrier. So I am not complaining about it. You get what you pay for.

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.

Flight details on public information screen were misleading and wrong.

The payment system was not working so was unable to connect wifi the entire flight

I didn’t have food and they don’t include entertainment. Not much leg room at all. Staff were great.

The boarding call announcements versus the Staff announcements versus the digital signage board on the out-going and returning flights WERE NOT IN SYNC. I was sent through check and re-checks 3 times. WHY?

Absolutely the worst airline. Can’t find anything positive to say. We were in business which is the same as most airlines coach

everything to do with KAYAK was terrible. Your customer facing departments are utterly useless, timewasting and unhelpful.

I ordered short ribs for main course. It tasted sweet, really sweet. Horrible.

When checking our bags we were told our bags would go through our final destination. This did not happen. When boarding, after group 3 it was a free for all, everyone boards. When served lunch, I asked for anything without dairy, I was given popcorn and gummy snacks. She said she would come back with more options, she never did. Also, when traveling through London, they don’t tell you your gate number until 1 hour before flight leaves, causing everyone to run to their gate.

When Stephen arrived with our wheel chairs - we were in excellent hands! He was such great help with getting our rental car and then reporting our missing luggage. When you are exhausted from traveling for too many hours, he was just what we needed to navigate everything! Give that guy a raise!

Full flight, but crew was great. No wifi and no seatback entertainment, so had to read...argh!

The screen didn’t work and I didn’t get the seat upgrade I paid $300 for. They were no help with that,
