Another interesting note regarding JAL availability in late March. I just got a notification today (I have alarms set for less than 4 F or A fare) so I went into experflyer and checked my flight (JL009 ORD-NRT on Mar 28) and the entire inventory for any class is 0. I checked the seatmap and only business class seem to be sold out. I also tried google the flight and they're not selling any tickets on this particular flight. Could the plane be sold out but just not reflected on seatmap? I don't think JAL will cancel this flight, but it's just a bit bizarre that the whole inventory turns 0 overnight.
