This belongs perhaps in Airports etc forum, but I thought I'd better not clutter up their nice orderly forum.
I was following the progress of a flight over Brazil when a THY 777 was heading the other way from Buenos Aires via Sao Paulo to Istanbul. For some strange reason I found this an odd pairing of cities as there don't seem to be historical links/communities at either end
Might it be that THY are offering their hub at IST as a gateway to Russia/Middle East/Far East without going through Europe to Sth American passengers ?
