Cambridge Air Travel
Although Cambridge has its own airport to the east of the city, there are very few commercial flights from there. Instead, London Stansted Airport in the south provides the easiest links, with London Luton Airport in the south west a further option.
London Stansted Airport is about half an hour away by direct rail link and the railway station is right next to the terminal buildings. There is a good choice of flights here, including both Easyjet and Ryanair.
London Luton Airport can be reached by rail via London Kings Cross with a shuttle bus from Luton Airport Parkway railway station, or by direct coach service. London Heathrow can be reached by rail via London Paddington, or by direct coach too.
