London’s new Elizabeth Line will open on Tuesday (24 May), although direct services to the airport will not commence until the autumn when tunnelling is complete. Until then, a change is necessary at Paddington for another Crossrail train.
A single journey from Paddington to the airport will cost £10.70 off peak and £12.70 at peak times. This compares with the £25 single fare for the same journey on the Heathrow Express.
A single Tube journey from central London to the airport costs £3.50 off peak and £5.50 at peak times.
