Airport
Travelled through Blackpool airport on our way to the Isle of Man in Oct '08. A little surprised how busy it was, saw international flights operated by Ryanair and Jet2 while we were there, I guess there are others too.
It's easy to get to by car, follow signs from the M55 but, if you intend to leave your car in the airport capark be sure to pre book, prices are very high otherwise.
