Nonstops account for about 28% of the award options in the data.
For Seattle–Chicago, the cash fare is the benchmark an award has to beat. The cheapest economy seat is a partner award on a United Airlines nonstop, so the lowest price is also the quickest trip. Watch the cash: about $319 in taxes and fees, well above the route's typical economy taxes, so more points and less cash can win. If the cash price is modest, buying the ticket is often the better trade. Transfers out of bank programs can't be reversed, so confirm the exact flight is bookable first.
Lufthansa Miles & More is cheapest in economy at 88 points on a United Airlines nonstop. Also in the mix: American AAdvantage and Delta SkyMiles. Even with Lufthansa Miles & More on top, a last cross-check before transferring is cheap insurance.
Nonstop award space on Seattle–Chicago spans two alliances: United Airlines (Star Alliance) and Delta (SkyTeam). That means partner programs in both alliances have a way onto a nonstop. The economy floor is a Star Alliance partner award: Lufthansa Miles & More prices the United Airlines nonstop. With just four airlines holding award seats here, a route alert catches new space faster than rechecking each carrier.
