Cons: Told us to pick up stroller in Dublin. Get there and we are told that is not possible. Of course we not have arrived at our final destination without said stroller. Seats are on the pitiful side of the spectrum and gets a bit old being nickled and dimed for drinks, sodas, food. . .

Mediocre 3.3

Pros: Not much

Cons: Our bags were lost, no apologies (in fact, the phone was put down on me twice), when the bags were returned after 24 hours, one was damaged and had to be replaced at my expense....no chance of a refund. My family and I will NEVER TRAVEL WITH AER LINGUS AGAIN....the worst airline in the world

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

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 the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes 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 can'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.

If you have 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.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days. Fares are subject to change and may not be available on all flights or dates of travel. Some carriers charge additional fees for extra checked bags. Please check the carriers' sites.
