Seattle to Istanbul (SEA-IST): nonstop upgrade & award space

Turkish Airlines flies the SEA to IST nonstop about 9 times a week. With Turkish Airlines flying most of the schedule, the long-haul premium cabin opens when that one carrier decides it does, which is why the calendar matters more than the search. 2LNR tracks award seats on Turkish Airlines across every SEA to IST date, so you can see whether a seat exists before you move points.

Departure and arrival times are local at their own airport, so an arrival can fall on a different local date than the departure; the duration column is the true elapsed flying time. A dash means the airline has not filed that value in the schedule data we hold. Aircraft are IATA equipment codes as filed, and can change up to departure.
