Airline reviews

I liked almost everything (e.g. ease of booking, price, punctuality, efficiency, friendliness, courtesy). A slam landing in Dublin airport took some of the gloss off it, though. Being able to paste here the text of the review of the same flight that I just wrote for Ryanair would make me feel better about Kayak too.

I liked almost everything (e.g. ease of booking, price, punctuality, efficiency, friendliness, courtesy). A slam landing in Dublin airport took some of the gloss off it, though. Being able to paste here the text of the review of the same flight that I just wrote for Ryanair would make me feel better about Kayak too.

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

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

Staff were very professional. Much better than the outgoing flight from Dublin. Seat cushions were practically non existent. Making for a very uncomfortable flight.

Flight was delayed by 1 hour 45 minutes. Aircraft was cramped, dirty and uncomfortable. Boarding staff more interested in charging you for oversize baggage than getting you on board. Overall not a pleasant experience.

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.

A delay of almost 3 hours. It was evident that the staff wanted us to board urgently, to the point of rudeness, to avoid paying compensation

It's not the staff's fault. The cabin crew do their best but the setup in Stansted Airport by Ryanair is poor. The herding of people like cattle is unacceptable before boarding and is something that's in every airport but only in Stansted have I seen the queueing of passengers outside the plane on the tarmac and the crew only turning up with maybe 5 minutes to depart. This is a resource issue . Yes prices are good but seemingly comes with a price of poor treatment of customers. I'll pay more next time

On time arrival but the aircraft had seen better days and needed a deep clean.

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
