Bring snacks. Double check with the airline that everything is in order. Never go through large airports like Heathrow with any layover that’s less than 3 hours. Small airports are preferred for layover like Dublin or Brussels.

Fine, the process or boarding was a bit slow but the flight itself was quick and smooth. Not over booked and pleasant overall

More check-in counters or faster processing. I arrived early but got to the gate just in time to board the flight, I didn't even have time to use the bathroom. The plane was really dirty, encrusted dirt is everywhere and the plane smelled bad when I entered.

I couldnot board the flight since my previous flight from Lisbon to Madrid arrived too late.

The flight was on the time and everything was very smoothi

Asientos y tener espacio para maleta de mano y no tener que facturar

Had no disruptions or delays. Did not order any food.

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.

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.

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.

all fine - did not have food - there was no entertainment

Delayed flight. Received notice from ryanair by email and via app but no such timely information available at airport from monitors or staff

This was yet another excellent experience thanks to Ryanair, it's ground crew, cabin crew and air crew. Although our flight was delayed by about 15 minutes due to the late arrival of the inbound flight, the crew did their best to successfully minimise the delay with courtesy and efficiency. I also commend Ryanair for its choice of destination airport in this instance: Seve Ballesteros Airport in Santander is a modern, compact, well-kep and well-organised airport, where passing through security and passport control was a doodle thanks to its friendly and efficient staff. So take a bow, Ryanair - and keep it up!

Everything went according to plan. Check in, boarding etc all were very efficient.

Boarding at Arrecife was commended way too early. Far too long for elderly to be kept standing on their feet. Otherwise we’ll done to all staff.
