Looks like that is whats happening - split PNRs.

We may not know what exactly happened here. But, in the case of a split, where I got the upgrade, what happens to the PLT upgrade priority? Is the PLT next in line or system puts in line with the other PLTs (based on request time).

In our case, upgrades were an hour apart. And I know (well 99% sure) that no one else was upgraded looking at the seat map. So was I the last EXP and PLT first in line? Or was the PLT just next in line with an EXP priority?

Just wondering...
