Heathrow to Stansted is one of the longer airport-to-airport routes at around 53 miles, almost entirely via the M25, typically taking 75 to 90 minutes. It's used heavily by passengers connecting from a long-haul Heathrow arrival onto one of Stansted's extensive network of low-cost European routes.
The M25 can be unpredictable at the best of times, which is exactly why we quote a fixed fare rather than a meter running against traffic you have no control over. We track your inbound flight and build in a genuine connection buffer, so a delayed Heathrow landing doesn't automatically put your Stansted departure at risk.
