A traveling companion paid just under 10K through Alaska for a JAL business seat. Trouble is JAL CS unable to assign him a seat after multiple phone calls, telling him he has to wait until day before flight. Their suggestion cancel through Alaska and rebook through JAL, at a now much higher price. I've booked JAL business seats with Alaska miles and was able to get assigned seating through JAL website after a week or so after booking. Suggestions?
