Flight crew made up time to arrive on time despite late arrival. They are pretty amazing - they got a plane hundreds of miles in the same time it took the ground crew to get my bag from the plane to the baggage claim.

Frankfurt is just an awful airport. Too many landings and not enough infrastructure. Also tired of planes having to park thousands of yards from the terminal. The time to get the bag is as long as the flight. Each about 55 minutes. There is very little about German efficiency here.

The customer service from Aer Lingus is the worst ever. This is our honeymoon and it got ruined. The flight was 3 hrs delayed, and they started rerouting people that had connection flights to London, we had a connection and randomly Wendy the service agent decide to not reroute us because we had plenty of time, of course we didn’t make the flight, we have been hostages of Aer Lingus for the last 21 hrs so far, but more will be added until we make it to Hamburg tomorrow at noon instead of tonight at 8.

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.
