Seattle–Toronto rewards discipline: redeem only when points beat what the ticket costs in cash. The cheapest economy seat is a partner award on an Air Canada nonstop, so the lowest price is also the quickest trip. Watch the cash: about $327 in taxes and fees, well above the route's typical economy taxes, so more points and less cash can win. When the fare is low, pay cash and hold the points for a pricier trip.
Lufthansa Miles & More is cheapest in economy at 88 points on an Air Canada nonstop. American AAdvantage wins business class at 18,000 points. Its first-class fare from 18,000 points connects, which usually means first on one leg only; read every segment. The other six programs include Alaska Atmos Rewards, United MileagePlus, and Delta SkyMiles. American AAdvantage takes over at business class, so the right currency depends on where you want to sit.
Nonstop award space on Seattle–Toronto spans two alliances: Air Canada (Star Alliance) and Alaska Airlines (oneworld). That means partner programs in both alliances have a way onto a nonstop.
