Update: FARE is GONE!!!
Remembrance of Days Past. This fare has been hanging around and I think it is time to travel for spring break to London.
Expedia has a fare for London listed as Iberia but actually on British Airways. Fly Houston – London Heathrow nonstop for $294 all in for dates through March or San Francisco-London Heathrow (LHR) nonstop for $420 all-in.
An extra $7 and you can fly American Airlines out of SFO with a connection in Chicago or New York.
I favor nonstop myself from San Francisco.
Update: Feb 14, 8am EST Fare is gone.
