I don't mean to rain on your parade but your choices may be limited. Just because the award booking window opens at 330 days, doesn't mean all flights will be available and all airlines will offer seats for award travel.

That far out, you'll be in good shape to get the dates you want but make sure you do some homework in advance and know which flights, airlines, etc. you prefer. Have first, second, and third options mapped out before you start attempting to book.
