OK 4.3

Pros: Food was ok

Cons: Who starts a boarding process 2h before the flight with only 2 counters, with no possibility to check in online (even for those without luggage) and no automatic machine? I'm very glad the company had the kindness to wait for us on the last call for boarding when you finally check your luggage 30min before departure. Should we talk about the politeness of your fight crew? In short, very disrespectful. Delivering the luggage took an extremely long time

BOS

Excellent 10.0

Pros: The crew was as amazing as they were 9 years ago when I flew Aer Lingus. The plane was very clean and comfortable. The entertainment that we could choose from very good. Something for everyone was provided.

Cons: One thing that I would like to see improved is for the announcements to be spoken slower than they were. The announcements were so quick that I could not understand what was being said. This should be an easy fix so I have no worries .

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.
