Are you sure the T-14 is still happening? A couple of hours ago it was 9am in Tokyo on Jun 8. In theory JFK-HND on Jun 22 should have opened. It has 5 F seats right now. Nothing is open. Jun 21 has at least 7 F seats on both JFK-HND and JFK-NRT, and if they opened something yesterday, in theory some of it would still be left. They used to let you get almost the last F seat at T-14.
