Not so good meals. For a 9 long-haul flight only one meal provided, other was a cheap candy bar. Other carriers do offer breakfast. Traveled with child and did not allow priority boarding at LHR. Limited leg room, I assume this already a trend well known by travelers.

Boarding was not done by groups, I end up storing my bag in the bin by the end of the plane while my seat was at the beginning and this was delaying my exit upon arrival. Not good experience having connected flight.

Short flight but had to pay for snacks or drinks on Aer Lingus.

The seat was comfortable on the newer plane and the in flight entertainment was excellent.

The airline features an upgrade yourself bid option that starts at a minimum bid. We went above this and got rejected, only to find there were still open seats. They tried to then upsell is at 4x the cost which makes the entire thing seem terribly dishonest. After calling customer service, they hung up on me. It’s clearly a scam to extract more pricing data from customers.

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

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 rentals 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.
