I'm meeting my wife next weekend in Mexico City and ideally in the MEX airport. However, I arrive in terminal 1 and she gets in to terminal 2.

I've read that I can't take the air train to terminal 2 without a boarding pass, so I can't meet her at her arrival gate.

If I take the ground transportation I assume I'll be outside security, so, is there an obvious arrivals gate at terminal 2 everyone arriving has to go through that I can easily meet her at?

Thanks in advance.
