Enough seat availability for us to move a little and so sit together - but the flight was half an hour late

Easy short trip from Faro to Cardiff. Exceptional staff. Early landing and straight through airport in 15 minutes from touch down.

I need assistance and I could not fault it at all. I suffer anxiety and I was always put at ease by assistance staff, and the banter was good. On board the staff was so very nice and kind and showed empathy. Thank you to them. It was my first time travelling since I lost my husband and was so grateful to them.

Food and entertainment were not available, so my rating on those items isn't actually correct. There should be a "Not relevant" or "Didn't use it" option.

Delay in boarding with no explanation why. Stood for about 40 mins waiting to board

Great flight just took some time to board even when lining up early for the flight, even taking off took longer then expected.

The flight boarded nice and early and this meant there was no sudden rush at the gate. The only down side was the cabin was very cold 🥶

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

Flying from Newquay was an absolute dream! Would 100% recommend flights from there!

Ryan air flight was good. Nothing to complain about. I had heard absolute horror stories about Ryan air so was worried about the flight but everything went smoothly. We have had two Ryan air flights with no problems. Last flight is Vernon come. Palermo to Milan. Fingers crossed.

I like the stripes, the more color the better I think you could even make more contrast with the stripes by filling in colors that create visual effect. The crew on both flights were polite well dressed, alert, good looking and very friendly. I never had a standing in line anywhere long for entering or exiting to my seat and it’s nice that people don’t bring too much luggage on the plane. The one thing I find is hard to manage is when a family or in general just being able to book a free seat if it is not for a dog, it shouldn’t be allowed. Since it is already very confined space on a flight overseas this can create slight conflict because there are sometimes free seats, which people then can freely use after cabin doors are shut. On the return flight, it was dark and by accident I stood on a paper bag with food in it that was placed on the floor in front of a seat next to me. I belong to the lady across the aisle and I felt terribly sorry once I found out there was still desired food in the paper bag. So I felt uncomfortable for getting into this situation. Otherwise I had a great time.

Not good due to rebooking automatically to a connection flight having very long duration due to 1st flight delays. Also seat booking originally paid by us and while rebooking time every family member was given different seats.

Upgrade prices could be more attractive. Business class was "empty".

Overall, we were satisfied with the Lufthansa flights to and from Rome/Zurich. Issue was the Frankfurt airport connection. It is HORRIBLE, but has nothing to do with the flight. Flight was very comfortable. Food was just OK. Staff was great and able to relax during the flight. Would definitely fly again!

Boarding was very good, crew attentive and friendly, seat size comfy, screen size nice. However, the seatbelt segment with the buckle is extremely short, which made fastening the seatbelt very complicated. Moreover, the bluetooth pairing of the audio system didn't work. It was not possible to have proper audio. The flight info software didn't work, too.

We sat in our seats on the tarmac for almost 3 hours due to storms. They would not give us water or a snack. We were to depart at 7.30 pm and it was about 10.30 when we took off. No dinner until much after that. Beef type noodle dish was terrible with about a teaspoon of beef in it. The breakfast sweet waffle with egg and sausage inside was horrible. An English muffin sandwich would have been much better. Food was the worst in all of our years of traveling the world.

They messed up my seat so I didn’t get the one I paid for

Flight attendants were fine, seats a bit hard but I use a cushion for extra support. The only issue was it was a bit too cool and I needed to ask for and received and extra blanket. I survived!!!

Very few things and/or people are excellent. It was very good.

Extremely uncomfortable seats. Experience was like a Frontier Airlines flight. Would not fly it again.
