[TEARELBO]

Hi UK friends, I'm in ireland, and travelling from manchester airport to leeds/bradford, next week, what is the best and cheapest way to do this by public transport.

Train to Leeds then bus to LBA

National express coach do this, man airport to Leeds coach station , 50mins stopover, Leeds coach station to lba.

www.nationalrail.co.uk for train times and prices
national express for buses.
If you book a train ticket direct with transpennine express and book an "airport advance" ticket then you can use it on the next train if your flight is delayed (advance tickets are usually only valid on the train you book)
