So I have collected 400k in miles since September. I'd love to go to LA next Xmas, on 27th, for a week. There are four of us. What's the chances? And best plan?
All you can do is check on a daily basis when flights are released, there really isn't a plan or best way to go about it. They might release some straight away, the might release some another date between them going on sale and the date of the flight, they might not release any at all.
Reward seats and their release are a great mystery in the main.
