Helsinki to Seattle (HEL-SEA): nonstop upgrade & award space

Finnair flies nonstop from Helsinki (HEL) to Seattle (SEA) just three times a week. A long sector flown three times a week carries its premium cabin in short bursts: space appears around schedule loads and equipment changes and is gone by the next one. 2LNR tracks award seats on Finnair across every HEL to SEA 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.
