The station opened on 19 July 1975 in the first phase of the extension of the Piccadilly line from Hounslow West to Heathrow Airport and it remained the terminus until Heathrow Central opened on 16 December 1977. "Hatton Cross" refers to the crossroads on the former coaching road leading southwest and is now applied to the overlying major road intersection immediately southeast of the station. On its opening in 1975, Hatton Cross was one of 279 active stations on the London Underground, the highest ever total; the number of stations in the network has since decreased to 270.
The station, itself in Hillingdon, serves a very small residential community in Hatton, which is in Hounslow. The nearby area is either within the airport or mainly comprises its associated commercial warehousing and light industrial premises. The platforms at Hatton Cross are in a cut and cover tunnel. The platform tiling on the central columns features patterns derived from the British Airways Speedbird logo. The station building, a brutalist, concrete-and-glass, single-storey box, incorporates a busy bus station, which serves the airport and surrounding area. Just to the east of the station the Piccadilly Line briefly resurfaces to cross the River Crane then descends back underground again. The station has payphones, wi-fi and a car park.
Connections: London Buses routes 90, 203, 285, 423, 482, 490, 555, H25, H26 and X26 serve the station. Apart from being a tube/bus interchange, the station, at a limit of the Heathrow free bus zone, which makes this interchange a busy one.
