Flying to Tokyo for the 6th time in 18 months Sunday....upgrade?
So I've been flying to Tokyo for work for the past 18 months. This will be my 6th trip. I'm an American flyer in the US, so I use my JAL flights to accrue AA miles. I'm Platinum for the 2nd year in a row. I was surprised that there's no upgrade courtesy with AA upgrades / miles when flying on JAL despite the fact that I accrue many of my miles flying JAL. I always buy Premium Economy which is quite nice on JAL: anyway. I typically politely ask at check-in if there are any upgrades available, and they always say no. Is there any trick or anything I can do to get upgraded in one direction? It's such a long flight and I'd love to be able to catch some more sleep. They're always very nice on JAL and I'm loyal to them for these trips...just not very liberal with upgrades. Any tips are greatly appreciated.
