Alsaka agent said on the phone to me today that there no bookable flights currently on JL. She said this is JL thing, until they open back up, not an AS thing.
She expressed her frustration seeing award space and spending time entering all the info for four people, only to discover that the system wouldn't allow her to fully book and ticket the reservation.
She suspects this will be resolved when JL opens back up...she said the same applies for KL and CX awards, not currently bookable..
