I'm looking at arriving on an international flight at 8:15am and departing on another international flight in T4 at 9:15am and wondering if this is possible.
Thanks!
You do not have to go though customs and/or immigration (or enter the UK) when connecting flights at Heathrow, even between different terminals.
However you do have to go though a security check again.
60 minutes is a very short connection time to allow between international flights at Heathrow though!
You may well make it, but you stand a significant risk of missing your second flight if you get any delays with your first flight, or with security.
