But you'll only be able to fly between September 12 and December 19, 2018 and on Tuesdays, Wednesdays, or Saturdays. And also note that this won't be your Thanksgiving flight home: Sale prices aren't available between November 15 and 29. You'll just have to book a fun trip you actually want to go on instead.
The other good news here is that Alaska Airlines isn't a budget carrier, so you won't be paying extra for that personal item and carry-on. Just make sure to book by Tuesday night at 11:59pm PT.
