I am booking a flight from London to Mt. Kilimanjaro airport with a very short layover and plane change in Nairobi. I am getting mixed reports as to whether you have to clear customs in Nairobi or Mt. Kilimanjaro. The flight is British Airways connecting with Precision Airways in Nairobi. The layover is only 1 hr. 5 min. and there aren't a lot of alternatives at the price of the ticket.
