As part of Alaska Airlines' sponsorship of SIFF, mileage plan members can get a 15% discount on most tickets when purchasing on siff.net, the festival web site. Just enter the promo code ALASKA. Though I've not tried it (I'm a SIFF member and passholder so don't need the discount), I'm not sure how the system would discern whether or not you're actually a mileage plan member. The festival runs through June 12, so there's still plenty of good stuff left to see (300+ movies on offer from 60+ countries). A lot of trailers are available on the web site. If the weather sucks this three day weekend, it may be perfect weather for a movie.
