Despite the hefty walk-on cost of Heathrow Express, there has been some good news of late. As of March last year, under 16s accompanied by a parent or guardian now travel free on the service. Heathrow Express also recently revised its pricing structure to offer substantial discounts for advance purchases, with tickets now available from £5.50: a massive saving on the walk-on price.

Otherwise, although a number of Heathrow Express discount codes have disappeared over the years, there remains a number of Heathrow Express discount codes still functional in 2016, and they may well be applicable to your journey (in some cases saving you a small fortune).

12% discount on any ticket combination – Mastercard holders only

Via this link, Mastercard holders can get 12% off any Heathrow Express ticket purchase until 31 December 2016. There is no need to actually use a Heathrow Express discount code, just click on the link and the discount will be applied.

Two adults together – DUO12

One of the most popular, and widely applicable, Heathrow Express discount codes is DUO12.

The DUO12 code basically means two adults can get a return at £27 each, rather than £36. That’s still pricey, but a substantial saving of £18 for the two returns (i.e. £54 instead of £72).

The obvious downside is it does mean you need to be travelling with another adult.

You simply need to enter the discount code DUO12 in the promotion code box when booking online.

Key terms:

• The same two adults must travel together at all times, in both directions
• Return ticket is valid for one month from the date of first scan
• Offer applies to Express Saver return tickets only
• Offer cannot be used in conjunction with any other promotion or discount
• Railcards cannot be used to purchase this offer
• Non refundable

Three adults together – 3RDOFF

If you are travelling as a group of adults, the Group Saver offer will saves you one-third, provided that 3 or more adults are travelling together. To benefit, you need to use the promotional code 3RDOFF.

Carnet tickets

These offer 12 one-way tickets for the price of 9, so you get 12 journeys for £198 (£16.50 each)

Railcard discounts

It’s easy to forget that you can also get a discount (usually 34%) with a railcard (National Railcard, 16-25 Railcard, TFL Annual Gold Card, Senior Railcard etc) or even an ISIC student card.

In conclusion, these discounts are all worth bearing in mind but if you can book in advance – do it. The savings are massive.

Failing that, there are a variety of Heathrow Express discount codes that should reduce your journey price substantially, but be sure to have a good look to see which one works best for you.

Other options…

Away from the Heathrow Express discount code option, Heathrow Connect from Paddington is also an option. If you are flying from Terminal 1-3, it is a direct (albeit stopping) service. You need to change trains for Terminals 4 and 5. At £20.40 for a return ticket (£10.20 one-way), it is potentially much cheaper than the Heathrow Express.

You can of course also get the tube to Heathrow, at the following rates from Zone 1:

• Peak: £5.10 (Monday to Friday from 0630 to 0930 and from 1600 to 1900).
• Off Peak: £3.10 (at all other times including public holidays).
• £6 cash

Don’t forget that you can also earn Avios or Heathrow Rewards points (exchangeable for airline points, amongst other things) when booking on the Heathrow Express. However, take heed of our warning on this point.
