Which airlines fly San Francisco to London nonstop

The cheapest way to fly San Francisco to London by phone
Pricing a San Francisco to London round trip takes 3 levers: the departure date, British Airways against Virgin Atlantic, and the Madrid one-stop beside both nonstops. The 2 carriers fly from SFO to Heathrow in about 10.5 hours across oneworld and SkyTeam, so each date prices on 2 separate networks. A Tuesday or Wednesday departure prices below weekend peaks on transatlantic calendars. The agent runs the full comparison on your exact dates; the search process is on the cheap flight deals by phone page.
One-stop routings that often beat the nonstop price
The one-stop against both San Francisco to London nonstops is Iberia through Madrid–Barajas. SFO–MAD–London flies oneworld, matching British Airways, while Virgin Atlantic sits in SkyTeam, so the 3 routings span 2 alliances with different fare bases. Peak London dates price the one-stop below both nonstops; shoulder-season dates narrow the spread. First stays on the BA nonstop, and the agent quotes all 3 structures with total travel time before you pick.
Last-minute seats on San Francisco to London
Last-minute San Francisco to London seats come from the British Airways and Virgin Atlantic nonstops plus the Madrid one-stop, priced within the final 72 hours. Late transatlantic fares turn on the departure window and the carrier spread: an early SFO departure against a red-eye, oneworld against SkyTeam. The agent checks all 3 routings, quotes the workable totals with taxes in, and tickets before the fare closes. The playbook lives on the last-minute flights by phone page.
Round trip and return-date strategy
Book a San Francisco to London round trip and the return date stays movable under the fare rules, with free cancellation in the first 24 hours under the DOT rule. The agent quotes the round trip against 2 one-way tickets on your dates and reads both totals aloud. The ~10.5-hour eastbound to Heathrow usually prices lower as a round trip, and later return-date changes follow the fee logic on the flight cancellation and refunds by phone page.
