Maybe I should have been a little more clear, but a more thought-out comment would be "in the context of eUpgrades, there is no such thing as linking two PNRs".
Well, I was wrong.
There's a Special Keyword that can be added in Amadeus.
LKRL, for LinK Record Locator.
It's much more than just a general remark.
I don't know if any systems will do anything special here, but there are 3 of us with identical itineraries on separate PNRs for travel in November, so I'm sure there will be plenty of schedule changes, and we'll see if we get rebooked on the same flights.
