I got this in my e-mail this morn.
The Travelzoo Newsdesk has found this outstanding offer from
Delta and other airlines:
SAN FRANCISCO--MARCH 19, 2009-- We just found spring fares
to Madrid or Barcelona from San Francisco at the lowest
prices we've seen in years.
Pay just $425-$461 roundtrip -- including taxes, for travel
through May. These same routes jump to as much as $1100 for
flights in June-August.
Madrid prices range from $425-$461. Barcelona prices range
from $432-$451. However, the $425 and $432 fares can be
found on the majority of dates. Prices tend to go up on
Friday and Sunday flights, especially in April.
These fares are unadvertised and could go up any minute. We
recommend booking soon for the best prices and availability.
