The only problem was there are games on the entertaiment system. The guy behind me played poker the entire time and poking the back of my seat. I hope they remove these.

The only problem was there are games on the entertaiment system. The guy behind me played poker the entire time and poking the back of my seat. I hope they remove these.

Delayed due to weather... fine. But then the board us. Rows 15 and back had to go down the stairs and back up the back stair entrance to the plane. No assistance offered. Then they inform us that we are delayed for paperwork for an hour. So why did we board? Then, about 45min later they inform us that it'll be another 60-90mins. Really? No wifi, no seat entertainment, no drink or snacks offered. And we were not allowed to deboard.

Great travel. Wonderful experience. Hope to do it again in the near future. God willing

Aer Lingus doesn't have plug ins for devices at each seat. They also did not give me a dairy free meal as requested and confirmed by staff. It was as if I had not requested anything. Otherwise, they were great!

There were a lot of empty rows. As a single passenger I should not have been seated with 2 others. The WiFi didn’t work. The Kosher meal was awful.

Both flights were delayed due to maintenance issues. Because they where late boarding all four of our bags where left behind on our last connecting flight.

Aer Lingus interior is not the cleanest. I've seen crumbs on the seat and wrappers on the floor when I boarded

Flightl was good and on time. Only problem was the quality of the air in the cabin,didn’t appear to be clearing the air circulation.

The transatlantic flight was wonderful. The regional reminded me of jet blue. Crazy and packed. Not enough overhead space and tough on elderly.

They lost my baggage on my connecting flight and we’re an hour late so I nearly missed it

What can you say Ryanair get you there,no frills Not so cheap anymore ..... but what is now days! Would use again as always. Good flight times for us.

Very unpleasant staff, disgusting service, ignoring requests, refusal to help

The usual average Ryanair flight, but we landed 20 min before due time, which was very good.

The flight boarded and departed Venice on time (more or less), the cabin crew were super friendly and efficient, the flight crew kept us informed of progress, and the flight arrived early in Dublin. All in all, this flight was as close to perfect as is possible to achieve. Well done, Ryanair. The fact that Ryanair aircraft arrive and depart from gates that are in the back of beyond in Dublin's Terminal 1 is a bummer - in terms of the length of the walk need on both ends of a return flight. But I suspect that this is not Ryanair's fault

On time but no water , milk or refreshments of any kind on board. Which is poor, especially with children and elderly on board. Toilets filthy,

The boarding process was fast and easy , but the airport sign was not up on the board, so it was hard to know the correct gate , on the airplane there was NO Snacks and NO water …. Everything needs to be purchase …. It’s not worthy for the price we paid !

Pros: "Quick boarding and arrived early."
Cons: "The seat was very very small for an average size human and the seat belt was on max.. No social distancing between seats"
Pros: "Rate. Didn’t like the charge of 55 pounds when I couldn’t check in on my phone. But the person at the desk was pleasant."
Pros: "Bought a seat 3 hours before check in and had a row to myself"
Cons: "Excellent Ryanair flight. 75% full. Very friendly crew."
Pros: "The captain had such a good sense of humour.. he was the most lighthearted captain ever- praise to all crew onboard and also amazing to the passengers."
Cons: "Nothing it was perfect for Ryanair.. always getting better"

Terrible. Missed my flight to final destination because of delayed British Airways flight. Had to spend 12 hours in airport and $1500 for new plane tickets

The crew on board were all very pleasant and happy to help. The flight had the old business class seats. The departure board in the business lounge did not update and kept on saying ' gate open' but never said boarding. When I got nervous about the departure time and walked to the gate I was told off rudely for being late.

Offered vegetable curry when it was actually tofu which I don’t care for.

The flight was good the crew excellent…but take off delayed three hours!!!

The boarding process was a disaster. No one respects the boarding groups—tired old aeroplane. There are no sockets to charge phones. The cushion seats are ancient and hurts back and gluts

Check in process was unfamiliar. While receiving assistance the employees supervisor berated him for not walking the area. Lucky for us, he ignored her and helped us check in. Did not know about the baggage fees with economy basic and spent 450 GBP (nearly$600) just on bags for a total of less than 2 hours flying time (50 minutes one way) on a round trip lasting less than 3 days. Customers check their own bags at kiosk and place on conveyor themselves. No reason for such an high cost of checking bags when customers do half the work. Some destinations it’s unavoidable, but will definitely seek other airlines before British Airways for future travel. Astronomically high price for bags. Our first experience flying British Airways and very, very disappointed. Completely overpriced for the services we received.

Both mine and my husband's chairs were broken. Also it took 2 hours to get our bags after our flight which was wild.

Having traveled from Canada through Seattle -London-Edinburgh with only carry on ( to keep trip uncomplicated ) We had to check our hand luggage at the gate as flight was full This was really annoying since due to their late flight in from Seattle we’d missed our orginal flight to Edinburgh and had been put on a flight four hours later We had no checked luggage with no need to go to the baggage carousel Very annoying

To take off on time but warned about a possible delay by enail which was good
