I need advice regarding the time it takes to get through customs at Heathrow in order to make a connecting flight on a different airlines/reservation out of Heathrow on the same day.
I am attempting to merge two travel itineraries/ideas. The short of it is that I am hoping to climb Kilimanjaro this August and then fly home to the U.S. using an existing reservation that I have from London Heathrow. My dilemma is how to best match up a flight from kilimanjaro to London Heathrow so that I can make that existing flight.
It looks like I could fly via Kenya Air from Kilimanjaro through Nairobi on August 27th-28th and arrive at London Heathrow at about 6:30am on August 28th. My flight from London to the U.S. is on U.S. Airways (Amer. Airways reservation) leaving London at about 10:00am on August 28th.
Does this give me enough time to get through customs at Heathrow, check in with U.S. Airways, and make my flight back to the U.S.?
Does this cut it too close?
Is this too risky?
