To celebrate the launch of an easyBus shuttle from Wednesday July 1, every ticket for travel in the first two weeks will be just £1.
There will be 90 services running daily from the first leaving Shepherd's Bush at 3.30am to the last bus departing Heathrow Central Bus station at 1.25am, transferring travellers in just 30 minutes.
Sir Stelios Haji-Ioannou, easyBus chairman, said: “Heathrow has welcomed the value of the easy brand.
"This new service will be good for consumers as it expands the easyBus offer throughout the capital.
"Now virtually every air passenger to London has the opportunity make great savings with easyBus.”
The £1 offer is valid from July 1 to 14. Normal fares start at £2. easyBus operates eight other UK routes.
