Luggage delayed and delivers 24 hours later … broken. No resolution… no response. We don’t have a suitcase for the rest of our 2 week trip

It was great like always had all my 3 luggage and I got to my destination safely

Everything was better but france airlines more better than them

Good leg room for people of all sizes. Pleasent crew.

WE didint profit of food , but for the other think all was good

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

Flight from London was delayed so missed the connecting flight. Taking 2 days to get to destination which should have only taken a few hours.

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

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.

We loved our flight crew were lovely and we were comfortable.

Had a lovely flight arrived 25 minutes early food was good staff we lovely.

Boarded and sat on plane for 3.5 hours before taking off, Updates infrequent and no refreshments offered.

I didn't have food, and there was no entertainment as it was a short haul flight, so can't comment on those, The head cabin crew member was addressing the passengers like a telesales person reeling off terms and conditions; we didn't understand a word he was saying. This is the second time this year we have flown with Ryanair, and both times we've had to carry our luggage downstairs to walk to the plane. As were both OAP's this isn't really acceptable. We have another flight booked for September to Lanzarote, so hopefully that will be better.

Smooth journey made good time. The aircraft was littered and did not look very presentable.

Flight was ok until there was a sudden juddering in the plane and a severe sudden loss of height. There were a lot of distressed passengers and not a single word was said by the pilot or crew.

Nothing unexpected considering it is a Ryanair flight. It does the job. Nothing above, at all.

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

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.

It is what you pay for. Always delayed. Very small planes. Hard to fly with kids.

Very timly. Great service !!! Pick up after meals can be swifter.

Straightforward boarding process. Pilot kept us informed during the flight, especially highlighting the fact that we would experience "significant braking" when we landed on the short runway in Florence. The flight attendants were pleasant. My chief complaint is that I was stuffed into a seat in the rear of the aircraft (row 29?). The seat pitch was soooo tight that my knees were hard against the seat in front of me as soon as I sat down. One inch more room would have made a difference. Thankfully it was not a super long flight, but it was quite uncomfortable and I had to work out the kinks in my knees once I deplaned. Is it really necessary to have the rows this close together??

Would not let me board with my fragile guitar so had to check it in. Who knows what the icicles did to it. Not happy. Had to run to catch my connection in Heathrow. After a bus and a train? Was asked by a guy in the middle seat to change my window seat with his girlfriend's middle seat further up in the plane and I was insulted. What nerve! The food was unhealthy and the seat was cramped. Could not wait to exit.

need more US friendly food options. Directions on getting to the next gate were terrible - resulted in long walks to the terminal and then finding I couldn;t enter there and had long walk back, then train to security then train back to where I started in the first place

We never made this flight due to the flight from Barcelona being delayed, which I have reviewed in a separate review. But I can tell you that the Delta Airlines flight that did get us home, I am extremely happy with them and their crew. The only one person that I would praise within the entire part of BA is the girl I spoke to in the call center in India. Who completely understood, was dedicated to a resolution and was a complete realist in the situation. Unlike some of the people who don’t care about the human element and stick you on a flight whenever. She got us home.

Wonderful service and comfort. Attentive and careful. The food was also better than US carriers. Highly recommend

Very good baggage check and boarding pass service at Heathrow. Boarding was well organized, given the number of passengers. Food was very good. Cabin temperature was lower than expected and we were not prepared. Overall good experience.

Paid for first class and was surprised that the seats were the same in economy except no one was in the middle seat. I expected an actual first class seat.

Captain handled the precaution of return to stand very well.

This flight had seats that were more comfortable than the trans-Atlantic flight I had come on. Boarding, however, was atrocious. There was no point in boarding groups since everyone ended up on the same bus to get on the plane. And the bus ride took forever to get to the plane. The snacks can barely even qualify as snacks. Make sure you bring your own or eat before getting on,
