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.

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.

This is truly the worst travel experience of my life. The UK ETA program had a technical failure, and I was stuck in limbo for 24 hours, unable to board my flight and unable to navigate anything in my itinerary. I had to rebook an entirely new flight and I’m now out doubled the money. Unconscionable.

OK, would prefer some meat for dinner, not just pasta although was tasty. There was only one dish, no choices

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.

It was a great experience. The aircraft is a bit dated but other than that it was great.

Last few years I didn't not have great experience with United Airlines.

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

We were delayed three hours from Montenegro to Vienna on our outbound flight and then rebooked an extra leg on our trip to the US. Our bags, which Austrian made us check in in Montenegro even though the flight was barely half full, didn't find us for ten days. Then, when we asked for compensation for the delay we were given the runaround that the flight originated outside of the EU. Next time we fly Turkish Air.

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

Great! They got my vegetarian meal right, flight was comfortable, they helped store my heavy luggage. Pleasant crew and flight staff.

Boarding was terrible. We were all cooped up in a small, claustrophobic space awaiting to be let out to walk to the plane. Very cramped and very uncomfortable.

Ryan air is a scamming airline. They advertise that you have to follow they baggage policy and their employees just do whatever they feel like. My most recent flight, i checked to large bags and just paid for 3 cabin bags and priority. Apparently, according to the staff, they knew the plane had too full in the cabin. This meant they had to target a select number of bags to into the hold. Now, a normal airline just offers to take your bag at the gate for you, it is their mistake. Not Ryan air, they just tell you the wheel of your bag sticks out 2 cm, we will charge you almost what you paid to check your entire luggage immediately, then tell you it’s on you. I would have gladly paid to check in the bags in the bag check in, where they told me the bag was good to go. Never using this airline again. I used to enjoy the quick direct flights but I will never use them again.

The baggage wasnt uploaded to the plane, lost baggage handling is very poor.

It would have been better if I was not ill so I didn't go and I didn't come back and I could not transfer my tickets to a later date as Ryanair stop flying from Manchester at the end of October till next year

Take off was great but landing is always with a bump.

They were extremely unprofessional and unhelpful at check in. They did not understand laws related to Spanish residents flying with family It was very discriminatory the way we were treated.

I didn't know that all connecting flights require online check-in two hours in advance, so I was fined 55 euros. This is a lesson learned.

They boarded us but somehow did not manage to record us boarding, so rather than check if we were onboard they removed our bags from the aircraft. I got a call from Ryanair staff in Dublin when I landed in Madiera asking me where I was!!! When I said I was in Madiera I was told what had happened. Our bags were to be sent to Madiera the next day via Manchester, they didn’t arrive. They are now due to arrive two days before we leave. I don’t see myself using Ryanair again unless I am forced to and even then I may just refuse.

The table at my seat was dirty, the crew was nice, the boarding was swift. An average Ryanair experience but this time the plane was not properly cleaned between flights.

After passing through boarding gates we had to wait for 45 minutes in a small space with no place to sit.
