From Flitwick, trains travel north and serve Bedford and southbound trains serve Luton, Luton Airport Parkway, Harpenden, St Albans, London St Pancras, Gatwick Airport and Brighton.

It was not until 1960 that British Railways added extra platforms to cater for extended stopping services between Bedford and London.

A number of peak hour services run non-stop between Flitwick and Luton.

Flitwick station has a waiting room, take away cafe, telephones, toilet and a car park.

The previous second entrance, situated directly onto the footbridge from Dunstable Road, which in 2016 had gates installed, is now permanently closed.
