If you're planning to go to SMOFCon 27 in Austin this December and live somewhere served by Alaska Airlines, you may be able to take advantage of a one-day airfare sale Alaska is running today only (Monday, September 14). The discount code is EC8752 and it's good for a 30% discount to/from Austin during the time period that includes this year's SMOFCon. I booked my ticket from San Jose to Austin this morning and it cost only $70 each way before taxes and fees. Mind you, that's the "nerd bird" flight -- there's only one flight per day on that particular route, and the timing is not good for people who need to be at the con on Sunday afternoon but also need to be back in the Bay Area that night, as the departure from Austin is at 3 PM.
(They're also running a 30% off one-day sale between Oakland and Kona or Maui (same discount code as above) Unfortunately, I can't take advantage of fares as low as $165 each way before taxes as I have no time nor hotel money for it.)
