On an ultra-long-haul trip like Seattle–Sydney, pick the cabin before the program. The cheapest economy seat connects once, and with no nonstop in the data, extra points can buy a better connection but not a direct flight. Taxes and fees on the economy floor run about $34, below the route's typical economy taxes. Stepping up costs about 1.3 times the economy points for premium economy and about 3.1 times for business. Before moving bank points anywhere, confirm the seat is bookable, since transfers are one-way.
Alaska Atmos Rewards wins economy at 42,500 points, premium economy at 55,000, and business class at 130,000. It also lists first class from 130,000 points on a connecting itinerary, often first on one leg only, so confirm the cabin on each flight. Qatar Airways Privilege Club is the only other program pricing the route. Business class also prices as a partner award, with one airline's miles buying another airline's seat.
On this route, oneworld carriers Alaska Airlines and Qantas Airways hold two of the four cabin floors, so oneworld programs are a good first check. Alaska Atmos Rewards sets the premium-economy floor as a oneworld partner, selling Qantas Airways seats at its own rates. On a connecting award, the airline named in the price table may fly only one leg, so confirm each segment's operator before moving points.
The data shows no same-metro alternate airports on either end of Seattle–Sydney, so the main airports are the ones to watch. Flexible on where you land? From Seattle, Amsterdam starts at 15,000 points and Athens at 30,000 at last check.
