London Heathrow (LHR) London Gatwick (LGW)
Heathrow to Gatwick is the most common London airport-to-airport transfer — around 72 km via the M25 orbital, but a direct National Express coach avoids two changes on public transport. Allow at least 4 hours between arrival at LHR and departure at LGW to survive UK immigration + M25 traffic.
