The different Heathrow terminals have different security requirements. I suspect it’s based on countries they fly to from each terminal, but it could be age if equipment.
It is frustrating for security to act like you’re a total idiot for following a process another terminal says is fine (like leaving very small electronics like Kindles in your bag).
Oh, well.
Indeed. Other airports in Europe even have separate terminals or areas for Schengen and non-Schengen destinations, with passport control and sometimes security scans again between them.
Bonus points to Zurich (Schengen but not EU, just to test the edge cases) - I think they have an airside metro where each car is segregated for a different security category of passenger.
That was one of my jokes going between terminals (always by bus): has this country thought about discovering trains?
Once leaving a terminal the staff said we’d take an internal bus and I asked if that meant we wouldn’t have to go through security again, but they just meant the same one as the rest.
All of our trips were non-UK-entry but possibly some terminals do have heightened security to meet one-stop-security requirements. Didn’t seem like it but can’t be sure.
