AF1 range/route/refueling?

Turkey Dinner Tour

Now, http://gc.kls2.com/ says the Great Circle distance KADW-BGW
is 6200m, and AF1 has a published range of ~~7300 miles.

But Great Circle would have taken them across multiple countries,
including those evil fried potato folks; so I'd assume they did
not use that route.

I'd also assume they would never get near trouble without large
reserves.

Was there an unannounced refueling stop? I know the 747B's have
capability for in-flight refueling but doubt they would do that.
