Turkish Airlines is offering amazing award availability between several US cities and Istanbul. I’d act quickly because 8 or more award seats in business class per flight simply will not last.
Turkish flights are feast or famine for award space. They opened business awards every day when they launched their San Francisco route. Historically Chicago – Istanbul has been the easiest flight on which to secure space. I’ve always had a tough time with Washington Dulles – Istanbul.
In the US they serve Boston, Chicago, New York JFK, Washington Dulles, Los Angeles, San Francisco, Miami, Houston, and Atlanta.
