I'm already imaging my ordeal in T3 on arrival:

First find a transfer checkin desk:

AI cronie: sir, you flight is in 6-7 hours, go away
I: but I have connecting ticket on AI, the luggage is already tagged by LH, see?
AI: no sir, please go away and go to domestic side
I: but they won't let me in departure only 3h advance allowed, no?
AI: OK, OK, give me your ticket, I'll take the luggage
I: can I also have a paid upgrade? (pull oout website printout)
AI: sir, we don't give upgrade
I: but I want to pay
AI: sir go away your flight is in 6-7h
rinse repeat etc etc

In the meantime AJs welcome cttee is waiting, the elephant is soiling the street and various officials are collecting cash from AJ because he is blocking everything
