Can I make a 1 hour 45 min connection at LHR on an international flight?
1 hour 45 min clears the 75-minute international minimum connection time at Heathrow, but you should still head directly to your gate. 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.

What happens if I miss my connection at LHR?
If you miss a connection, British Airways and most other carriers have transfer desks in the arrival terminal (especially prominent in T5) that can rebook you without needing to collect bags first if you remain airside; if you've been forced landside, use the airline's rebooking desk in the terminal you land in.
