Heathrow Rewards is the loyalty scheme for the shops, restaurants and bars at London Heathrow airport. Following a recent restructuring, ‘My Heathrow’ and Heathrow Rewards are now integrated into one platform and one log-in. How do you earn Heathrow Rewards points? Heathrow Rewards points will only expire if you haven’t made a transaction in the previous three years. If you are a regular Heathrow shopper, or a regular user of the official car parks, or a regular user of Heathrow Express, then you should join Heathrow Rewards.
