Tips for 50 min Connections
If your itinerary is entirely on British Airways within Terminal 5, connections can be genuinely fast since it's a single, well-organized building.
Any connection involving Terminal 4 should be given extra buffer, as it's physically distant and served only by rail or bus shuttle.
Check whether your transfer is 'airside' (no immigration) or requires exiting to landside — Heathrow's transfer routing varies by airline alliance and terminal pairing.
Security queues can be unpredictable at peak times (early morning and evening banks), so don't assume the posted MCT accounts for a bad day.
Use the free inter-terminal transit trains rather than walking whenever offered — distances between T5 and the central terminals are much longer than they look on the map.

High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
Getting Between Concourses
Terminal 2 and Terminal 3 are adjacent and connected by a covered walkway (10-15 minutes on foot). Terminal 5 is linked to the central area by a dedicated driverless transit train (Heathrow Express-style pod), while Terminal 4 is the most remote and requires either the Heathrow Express/Elizabeth line rail link or an inter-terminal bus, both of which involve exiting to landside transfer areas and passing through security again at the new terminal.
