As he drives on M25 and flight is is Europe it’s likely to be one of those 2 airports. He is leaving now, so an hour to get to airport / park / blah blah leave 2 hours in airport max so looking at flights around 2-3pm ish. Expect he travels a lot and might only do carry on... could be slightly earlier...What? You're coming to Hungary?
Edit: it could be Stansted to Dubrovnik
