Det verkar som en indonesisk medborgare som reser genom Heathrows flygsida till ett annat land som du inte behöver passera genom gränskontroll / invandring och behöver därför inte ett transitvisum.
Jag måste byta terminaler på Heathrow. Kan jag flyga på sidan?
Heathrow’s terminals are connected by dedicated buses that transport passengers from one terminal to another airside. If your baggage has been checked through to your final destination, you will not have to pass UK immigration control; the buses are part of the airport’s internal airside transit system.

You always pass through border control if you:
- leave the main airport building for any reason
- need to collect your bags and check them in to your onward flight
You must also pass through border control if both:
- your onward flight leaves on a different calendar day to when you arrive
- there’s nowhere for you to stay overnight in the airport, for example in a transit hotel
