Yea, booked via an All Airline award, which sucks, but let's me change for no fee. But the route was for a 20K mi trip and I am at 19964 right now. I was going to go around the world but was 100K mi short, I now have those miles, so maybe I can reroute. Already SIN-NRT is J as there is no F but at least it's JAL's new J. Frankly the basic purpose of the trip was to fly CX, so if I change, it needs to respect that one rule. I was sort of thinking:

ORD-LHR-HKG-SIN-NRT-ORD, or reverse, so I could get into the Concord room. Bummer, more planning and on my day off
