What if I attempted to make the change after arriving in Tokyo? Would I still face the same issue with fare construction, or are all bets off at that stage?
my ideal scenario would be to attempt a SDC immediately after arriving at NRT so we can get a couple of extra hours in Tokyo and store our luggage at NRT, then call again to try to get the W fare and upgrade to new Polaris on the NRT-SFO route. I know the odds are low, but I’ll give it a shot
