That’s an early one so the total hours will be interesting.
Looking at the equally old PH-BFG retired two months ago BFH likely has accumulated north of 135.000 hours/18.000 cycles. Its certainly among the dozen aircraft with the highest flight hour count ever, no matter what type. And likely all of these are/were 747s. The only type I can think of that perhaps come close could be some early-built Fedex DC/MD-10s though I am unaware of their hours.
PH-BFH was 3 months longer active, compared to PH-BFG
PH-BFH was one of the "easy to convert" combi's and has been operated in the combi configuration until July 2009. Thereafter she was operated in the full pax configuration.
Because of the higher flight hour/cycles count of KLM's combi fleet (more flight hours, less cycles. average longer stretches ) it is to expect that PH-BFH has a slightly higher flight hours count, with slightly less cycles than PH-BFG (dedicated full pax).
The Fedex MD10-10/30 fleet has a relative low usage and are not even close to the flight hours of KLM's 747 aircraft and all MD10's will be phased out in two years time.
The highest count I could find was still below 100.000 hours.
