No way to add a bag without getting in line at the counter, which took at least half an hour. No WiFi.

I was upgraded to business class. Seats same size but better food. Polite service.

The crew was attentive. The food was delicious. The flight was smooth.

The preboarding and the gate organizing management was poor, unorganized and mismanaged. While standing in the business line I kept getting ignored and the personnel kept checking in others, right in front of me until I finally spoke up and pointed out their clear signs of ignoring me while patiently waiting to be checked in. Once checked in the gate the personnel kept chit-chatting and not managing which group is to board, being totally nonchalant, unorganized and behaving amateur-like . Very unprofessional and unlike the quality the Austrian Airlines brand otherwise provides. The crew on the plane are always fantastic and the best. What a shame the crew on the ground was so mediocre.

Absolutely the worst food I've ever had on any flight. Otherwise, the flight is OK - just your regular transatlantic economy. Condor should stop saving pennies on meals. They save a penny, lose a dollar.

The layover period at Frankfurt of one hour and forty minutes was not enough time to clear the two-hour line at passport control: we missed the flight to San Francisco. Condor did a good job rebooking us that same day, but our bags ended up in Los Angeles.

Boarding by bus - this is 2026! Luggage did not board the plane though we had over two hours between flights. After it was located it didn’t fly immediately but waited one or two flights until boarding to fly yo Belgrade.

The airport gate in Lyon was an insult to human dignity…. Shame kn the French authorities

Excellent flight. The crew was exceptionally attentive and organized. Attention to details is unmatched.

Tight connection from Austrian Airlines made this challenging. Our luggage did not make it, delivered the next day at noon. Flight itself was very full, not especially comfortable.

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.

All great. Very efficient. Good emails that kept us in the know

I paid for priority (2 bags) and because I had 2 backpacks the boarding crew jumped to the conclusion that I had a non-priority ticket and had one bag too many. The person who spoke to me was quite rude and told me to leave the line without looking at my boarding pass that I was trying to show him. I queued to have my bag sizes checked - neither of them are oversized, in fact, either of them can fit under the seat in front of me but I paid for priority because I wanted to bring two. In the end, the same person had to speak to me and then said "you have two bags" to which I replied I had paid for them and when he checked my boarding pass he did not even apologize for the trouble.

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 was raining and we got all soaked because the staircases didn’t had a roof

Well... Our flight departed with more than 3 hours delay from Beauvais.

Would have been a very good flight, but busses did not meet the plane at the destination airport (NAP/Naples) for nearly one-half hour after landing. Clearly the airport concessionaire’s fault, not RyanAir’s.

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

Very good, staff seemed to check random cabin bags for size pre boarding.

We missed the flight due to very slow security control and lack of last call announcement. We only found out at the gate that the gate is closed. Altogether 14 or 15 people missed the flight FR4500 from Cologne to Dublin.
