Over the past 3-4 years, snagged 3 F JAL awards USA-TYO. Ended up cancelling each one, as 4-5 days from departure nothing had opened up on return options.
This morning, up popped an elusive F return in May. I figured it would be phantom, along with everything else I tried to book today. Miracle of Miracles, it went through, and ticketed. We'll see if I have better luck on grabbing an outbound than have with a return.
It's to ORD so a not a new bird - but ORD seems to be all there is right now.
