Try Ryan air. When i went to Dublin early 2008 i paid 4.04 pounds. And the 4 pounds was because i used a credit card :P But i flew through leeds bradford airport.

thanks guys.

I checked Ryanair, and as Maria noted, they offer 4 pounds flight. With charges and a bag, it adds up to around 40 pounds.

Since a train and a night ferry (providing a good night sleep in a cabin and arriving to Dublin in the morning) would cost less and have the benefit of not having to pay for a night at a hotel, I would assume this is my best bet.

David, you know any of these train & ferry things? I just don't know if I can trust it, and I won't end up on some ghost ferry that will sink in half way with a pirate as captain.

Are you sure you get a cabin for that price? I'm pretty sure you have to pay extra for them, and they're usually around £200 (when I've looked before). It's only a 3.5 hour crossing maximum. Their benches are fairly comfortable though - I used to do that crossing regularly and slept like a log every time.

The train/boat fare is called Rail and Sail and it is definitely legitimate - it's to encourage people to take the train and the boat instead of flying. There's a Rail and Sail website which you should use - I don't know whether any other websites are or not (you can find details on either the Stena or Irish Ferries website). Note two things: firstly you usually have to travel on a specific train, and if you don't you'll have to pay rather a lot. Secondly, although your ticket will probably specify a ferry, that doesn't always equate to a reservation on that ferry. It is very rare for a ferry to be full but it did happen to me once, travelling on the fast ferry at the start of July. I got on anyway as some people didn't turn up so I wouldn't worry abou tit.
