When to go
Departures from San Francisco follow the American calendar. The rush builds through late spring and the summer school break, then returns around Thanksgiving and the December holidays, when everyone wants the same seats. Fares are calmer in the shoulder weeks between those peaks, and midweek departures usually cost less than Friday or Sunday ones. On the European routes served by British Airways, Lufthansa, KLM, Swiss and TAP Portugal, demand peaks in high summer, so booking well ahead helps.
