Book your Heathrow Express tickets early

Heathrow Express is London’s most expensive rail link. The usual fare from Paddington Station to London Heathrow is £22. You may argue that for a speedy 15 minute journey the ticket price is well worth it. Now, however, if you book 90 days in advance for weekend travel a one-way ticket will cost you just £5.50. If you purchase your one-way ticket 14 days in advance the cost will be £12.10.
