There is a super fare war to Europe going on as of the morning of Oct 14. Cities include Zurich, Rome, Geneva, Venice, Dublin, Barcelona, Madrid, Paris and others. United, USAirways, American, British Airways, Swiss and more. There is no telling when this will end, but fares are valid for travel thru early May. We've listed as many as we can but we're showing a lot of actual bookings on our Twitter feed @airfarewatchdog There's even a fare from SFO to Dublin for under $500 round-trip!
Fares are generally in the $500s and $600s RT, even from Seattle and Portland OR. It's valid from small and large airports. Travel is thru early May. Fares are in some cases 50 to 60 % less than "normal" for spring travel.
