Manchester Airport is the biggest airport in the UK outside London and very well serviced with all major international airlines landing here. There are two main train stations, Victoria (northern Manchester) and Piccadilly and you get trains to any major destination in the UK from here. There are also regular buses or you can rent a car or motorbike.
HOW TO GET AROUND MANCHESTER
The best way to see the city centre is on foot and the city has a very efficient public transport system and you can get around the city by tram, bus or train with relative ease. You can also take a taxi (quite a bit cheaper than London) if you need to.
