For Boston–San Francisco, the cash fare is the benchmark an award has to beat. The economy floor is a partner booking on a United Airlines nonstop, with no connection to trade off against the points. That seat adds about $289 in taxes and fees, well above the route's typical economy taxes, so weigh points and cash together before booking. Run the miles-or-cash math each time: a cheap fare usually beats spending points. Hold off on converting flexible points until the seat is confirmed bookable; there's no undoing a transfer.
Lufthansa Miles & More wins economy at 88 points on a United Airlines nonstop. American AAdvantage takes business and first class at 25,000 points each. The other six programs include Delta SkyMiles, United MileagePlus, and JetBlue TrueBlue. The winner changes at business class, so match the program to the cabin before moving points.
The Boston–San Francisco nonstop is contested on points: United Airlines (Star Alliance), JetBlue, and Delta (SkyTeam) all show award space. That gives partner currencies from both alliances a way onto a nonstop. For connecting options, the better-priced awards in the data connect in New York and Los Angeles. Lufthansa Miles & More sets the economy floor as a Star Alliance partner, selling the United Airlines nonstop at its own rates.
