Mediocre 2.0

Pros: There wasn't anything special about this flight to like, unless you like leaving late and no leg room.

Cons: Try leaving on time for once, I nearly missed my connection because Aer Lingus is terrible at on time departures. I'm just under 2 meters tall, the seats were so tiny my knees were pressed into to the seat in front of me the entire trip.

Okay 5.6

Pros: Plane was held for at least 40+ min for additional passengers. I was in First Class and no drinks were offered until another passenger complained and then the flight team took a a burden to have to offer anything.

Cons: New Flight crew.

Good 7.2

Cons: I had a tight connection, but made it to the gate in time. I walked down the jetway to what appeared to be a locked door, with no one there to guide me on how to board. It turns out there was a stairwell at the end of the jetway, which was to take me to a bus on the tarmac. This was very stressful.

Pros: Nothing

Cons: The last 4 flights with Aerlingus have all been at least 2 hours delayed to London. People give out about Ryan Air but I have been flying with them to France 2 a year for the last 4 years and I only had one delayed flight because of air traffic controllers

DUB
SEA
Okay 4.3

Cons: The flight attendants were not helpful or attentive. A nine plus hour flight and they offered drinks once, picked up garbage once and when we tried to give them garbage before landing, told us to put it in the seat pocket or toss on the floor! It looked like the plane had been trashed when we exited

Pros: The price.

Cons: You have to pay for confirmed seats, and the seats are uncomfortable. No free beer or wine on international flight and the ticketing in Dublin was SUPER slow!

Prices are per person, are for e–tickets and include all taxes & fees in GBP.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller
At KAYAK we don’t set prices, so it’s not possible for us to guarantee what other companies are selling.

We aggregate tons of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we don't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car hires can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find on occasion that certain prices are no longer available.

More questions or if you have a bad price to report to us
Please send us an and someone from our team will get back to you promptly.
