From boarding to disembarking, the whole operation was very efficient.

From boarding to disembarking, the whole operation was very efficient.

Passengers next to me insisted I change seats so they could sit together. I had to frequently move so that when the sear belt sign was on I was in my proper seat! I was returning from helping my mum with my dad's things after his sudden death and didn't feel like arguing with the other passengers.

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.

It was appalling, full of young people who were drunk and disobeying instructions to sit down. Crew did nothing to enforce. There was a Ryanair pilot sitting in the aisle opposite me who talked through out the safety briefing so loudly I couldn’t hear. Whole thing felt unsafe

Flight was fine, crew were good, cabin director spoke far too much; disembarking at Dublin Airport and entry into the terminal building was just dreadful, like entering the back door of a neglected factory building. What an awful impression it must give to first time visitors to Ireland.

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

Cabin crew couldn’t be less interested. Cabin manager was the most arrogant and the rudest I’ve encountered in many years.

Crazy long boarding times, messy, inexperienced, overworked, and visibly tired crew, very uncomfortable seats and no compensation for delays.

The worst flight ever. Sitting in plane for 4 hours delay and then they change crew. No water or food offered to any passengers including children in that time. Only 2 toilets out of 3 operating for flight with 200 passengers. Only enough food available for about 7 rows of seats depending where you sat you might be lucky. Cabin crew very unfriendly.

everything was perfect! plus so much leg room w all the empty seats near me :)

All was good, except my USB charging did not work, so my phone got drained and I could not charge it. Same happened to my neighbour.

I liked Quiet people around me. Crew could have helped people with overhead luggage so they aren't moving other peoples bags around and causing problems for people that had there bags there first

I paid extra for more comfort, didn't get any better than any other seat, tv didn't work on both seats, it'd

Flight cancelled support worse than useless. Asking me to drive back and forth between terminal, I was expecting supervisor call within 30 minutes, never happened.

They didn't open the Check-in desks for almost an hour after they should've been open (even though encouraged us to check-in our carry-on luggage because it was going to be a full flight). They alerted us that the flight would be delayed but slow-rolled informing us of the extent of the delay...which ended up being over 3 hours. As a result of this, I missed my connecting flight and had to stay over-night in Munich when it would've been a lot better for me to just stay in Warsaw another night....Lufthansa wasn't done with me yet though as I had more bad experiences with them after getting to Munich.

The plane was delayed by two hours in Chicago which led to us missing the next flight. Lufthansa rebooked the flight and booked us a hotel for the night in Frankfurt. The level of customer service and getting us taken care of was superb. The flight crew and the service on the ground was superb.

Efficiency of staff, and comfort and cleanliness of aircraft was all great. Maybe a hot drink without payment at that time in the morning would be good!

Stop charging for alcohol overseas flights and start taking cash again not everyone wants to pay with card if the person is bigger give him seat on the outside seats not the middle in between the people is common sense and mainly if you fly for Lufthansa provides the sam service and experience...

good entertainment package but rather small seats for business class
