There has long been a theory that, on a mile-for-mile basis, the Heathrow Express costs more than a trip to the moon.

Without crunching the numbers, I’d probably take that with a small pinch of salt. However, I can confidently state that prices for the 15 minute journey have historically been eye-watering. This generally led to a scrabble to find any applicable Heathrow Express discount code, to get some sort of reduction on the fare.

Fortunately, all that has now changed with the arrival of a solid set of advance purchase tickets. 

Provided that your single ticket is on a specified date (in the case of a return ticket, that need only be the outward journey), you will be able to book tickets at the following rates:

90 days in advance

• Standard Class: £6.99 single/£11.90 return
• First Class: £9.99 single/£18.00 return

30 days in advance

• Standard Class: £10.75 single/£17.50 return
• First Class: £14.75 single/£26.50 return

7 days in advance 

• Standard Class: £16.10 single/£26.25 return
• First Class: £22.10 single/£39.75 return

Compare that to the walk-on price:

• Standard Class: £21.50 single/£35 return
• First Class: £29.50 single, £53 return

(+ £5 if you buy on the train)
