Agree that the VIP services I checked so far seem useless and rip you off quite good...
What I believe is most important is a fast track/dedicated/private line at the transfer security. Does anyone know, whether there is such a fast track? What I have not done so far is sending an eMail to AA2000 to see if they are able to help. Especially if we run only a few minutes late, it would greatly pay off to have somebody that can call the gate announcing us hurrying there.

I will definitely check if the Plat hotline is willing/able to make a note into the booking mentioning our short connecting time.

A minor but nevertheless positive aspect is that when making a mock booking for tomorrows flight (having provided all relevant information in the booking), I was able to complete the OLCI and receive the final BP, not just a checking confirmation or a document saying to pick up the BP at an agent. That means to me that if there is a passport/document check, it will happen at the gate, which should not be a showstopper.

Another question: when looking at the arrival and departure gates of LH510 and KL701, I see that both arrive and depart in "Terminal IA".
My understanding was that int'l departures is from the new international departures terminal while for arrivals there is an arrival terminal. So far, I imagined that as being two connected but separate buildings.
Considering both arrive and depart in "Terminal IA", does that mean that you stay within the same building but depart from a different level? That helps me to orient myself, whether I look for elevators/escalators or long hallways.
Unfortunately, I find only outdated maps of EZE (ifly.com for example).

Will definitely report whether we made the connection or not. Some elements are not in our hands, but I remain optimistic. If needed, I'll revert to my superpower of polite line pushing
