I've seen International E-Fare regularly out there 4 weeks as part of the regular International listings.

Domestic always has a current "this weekend" and often (also city dependant) a "next weekend" listing.

But on Internationals...this is nothing new, in my experience. In fact, I don't really recall seeing many "this" or "next" International E-Fares at all. Aren't they always at least 2 weeks out or more?
