On time departure; arrived early into Faro. Air Malta operating flight, crew friendly and efficient.

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.

There isn’t any entertainment. The food and drink was available for a price. I didn’t buy any.

It would be nice to have power to charge phone.

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 flight arrived within 15 minutes of schedule. We hate the cattle-like boarding process seen often in Europe. After your boarding pass is checked by the airline staff, you wait standing up in an area with no seating for several minutes.

Great flight, departed only 10 mins behind schedule off the aircraft and through security in less than 15 minutes. Love flying from Cardiff so easy a quick from entrance to duty free in less than 10 minutes 😀

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

I haven't had a ok flight with Ryanair in so long!

Staff were friendly and flight was on time. Free drink and snacks would have been appreciated.

Flight delayed but lack on information at the airport - only knew from looking at flight radar Other people queuing ages before a plane was there as staff not informing them of delays Usual issues with boarding people haphazard What is the point of priority when they don’t stick to it and all held like cattle just before getting on plane

The flight was on time, great value and very helpful crew. This direct flight was the most convenient I ever had coming to Sarajevo over the years. Will definitely use this flight again in the future without hesitation.

Very late to leave, poor communication on expected departure time and when boarding actually started.

Cheap flight but I didn't like the almost one hour delay because of paperwork!!!!

Gate is far at Leeds Bradford Airport. However, as the flight was less than half full, it was calm and not stressful. Great take off and landing. Friendly staff

Boarding was started early and we were lined up in. A glass tunnel on the tarmac we were left standing there for an hour with no information the flight left and arrived 30 mins late

It was great. We arrived a few minutes late but the crew were concert and kind about it. It was a nice smooth fly thanks be to Jesus. I prayed for smooth flight and Yahuwah answered my prayer.

We bought tickets for £30 from kayak but we paid £55 for check in to rayan , they slaught us

Flight was delayed so long we missed our second flight. Entire trip had to be cancelled. Ryanair refused to help us.

Boarding was like being hoarded like cattle, all penned in in an area way to small
