In a couple of weeks I'm taking the 9 pm flight from SEA to LAX. I was unable to pick my seat in advance, which leads me to conclude the flight will be very full and perhaps oversold.

So now I'm wondering if I want to volunteer for a bump. I've heard that the compensation on this route would be a $200 voucher. No bad, certainly not as good as the old BTTs though. However, the next flight out would be 6 AM the next day and SEA is a 3 hours drive from my house. If there's no hotel voucher, the cost of the hotel would eat up a large part of the voucher. What is Alaska's VDB policy when the bump is overnight? What about IDB? I read over the info on Alaska's site, but it appears to be somewhat vague (probably to allow the GAs some flexibility depending on the situation).
