Perk alert: Star Alliance Gold frequent flyers are eligible for a free Heathrow Express upgrade to the train's Business First class carriage. The popular promotion is continuing throughout 2020, and provides a premium bookend to any business or first class flight into or out of London's Heathrow Airport.
After all, the Heathrow Express is the quickest and easiest way for business travellers to scoot between Heathrow Airport and Paddington Station, where you can settle into your hotel or hop a Tube train or an Uber to your final destination.
And even though it's a quick non-stop journey, being able to step up from the standard Express carriages to Business First is quite a treat.
Located at either end of the Heathrow Express, these swish carriages offer more legroom than the regular 'economy' carriage, wider seats, a personal table and even an AC/USB sockets at each seat in case your device needs a fast top-up.
They're also less crowded and therefore quieter than regular carriages. So what's the trick to getting a free first class bump on the Heathrow Express?
All you need is to hold Star Alliance Gold frequent flyer status with any of Star Alliance's 26 member airlines.
That's a sizeable roster and it includes the higher loyalty tiers at Air Canada, Air New Zealand, ANA, Air China, Austrian, EVA Air, Lufthansa, SAS, Singapore Airlines, Swiss, Turkish Airlines and United Airlines.
Then, purchase a regular full-fare Heathrow Express ticket for standard Express class – it can be either a £22-25 single or a £37 return – but when you board the train, make your way to the Business First carriage and settle in.
When the conductor passes through, simply show your ticket and your Star Alliance Gold-grade frequent flyer card (or the digital card on your airline's own smartphone app).
