OK. Fair enough. But your example does not include the PALL codes for VIP1/UPG1, so we don't get to see it in action.

I'm guessing, an example would see a VIP1/UPG1 Y above all other VIP1/UPG1's.

But looking at the example here...

we clearly read, "ordered by date and time of request" and nothing do do with, also FARE INVENTORY.

I know it's true. You wouldn't say it otherwise. I'm just interested in seeing... I guess... in seeing it stated, or exampled some place else.
