Sometimes a technical stop to refuel is required for the 767-300ER due to wind conditions, especially is the piece of metal is rather full, which is often the aim in the charter business.
However this usually mostly happens on the way Asia-Europe, not as often on the Europe-Asia segment. You'd have seen this on NG
service in the times of the 767-300ER ops a few years back. And maybe also this winter according to another thread.
I guess that a stop in SHJ
particularly is a sweet way to fill the machine with rather cheap jet fuel as well. A nice treat in these days of golden barrels.
Sobelair (Q7) of Belgium (now bankrupt) also had to do stops (VIE
,...)once in a while on the way back from HKT
when they were running 767-300ER charters there.
