Maybe not Sabena but certainly Sobelair, their charter associate. Should also mention Caledonian, British Airtours' successor. I don't know if Air France and Lufthansa ever involved themselves with this sort of business, likely leaving it to the likes of Air Charter, Euralair and Condor.
I did fly on an Olympic 732 to Heraklion in 1990...but only from Athens. I don't know if this fleet ventured beyond the south east Mediterranean.
