Luton Airport train journeys start with the DART
Luton Airport Parkway is not inside the terminal. Thameslink says the Luton DART takes under four minutes between the airport and Parkway, and that a through-ticket booked to or from “Luton Airport” includes the DART.
From Parkway, direct Thameslink services run to central London stations including St Pancras, Farringdon, City Thameslink, Blackfriars and London Bridge. Current journey pages show the fastest Parkway → St Pancras services in the low-to-mid 20 minute range.
