Oops, I forgot some;
Scibe (of Congo) has one passenger 707 but it has not been reported in service. Aero Asia of Pakistan sometimes leases Romanian 707s for passenger flights. Sudan Airways still has one passenger AC but that's not seen in service for ages. Slovtrans of Slovakia also used to have one. And Bin Mahfooz of Gambia has two. They are occasionally seen on hadj-charters from Africa. But for scheduled services, I think you only make chance with Iran or Luxor.
And Ben, I've flown on 2 DC-3s (Dutch Dakota Ass and Era Airlines in Alaska), a Constellation (1947) of MATS, a Viscount, 2 1950s Convair 580s (Era and Frontier), a Lockheed Electra, a 1960 720B, a 1962 Friendship... it's a hobby of mine to fly vintage stuff.
nobody has ever died from hard work, but why take the risk?
