I’ve long said that it’s a myth that the best award availability is right when airline schedules load — the date for which varies, but is often midnight 331 days in advance of travel. People used to get up at midnight, call the airline, and when the space they want isn’t open think, “Drats! Someone must have beaten me to it!”
That’s not how it works at all. Some airlines do of course load some award space when they first add flights into their future schedule. Not all airlines do. And not all airlines load seats and call it quits.
What’s strange though is that it appears there’s not a single saver award in any cabin on any American flight yet for January 2017.
