On 20 May 2018, TfL Rail took over the services operated by Heathrow Connect as a precursor to the full opening of the Elizabeth line. Fares on the line are now integrated into the TfL fare scheme, and therefore match the fare scheme of London Underground services, with the exception of a premium for single journeys to and from Heathrow using Pay As You Go (Oyster and contactless). Passengers are able to use Oyster cards, Travelcards and Freedom Passes to travel between Hayes & Harlington and Heathrow.
