Yesterday early morning - quickest MEX transit EVAR. Arrived approx. 420am at gate. Darted to migraciones (T2) as you just never know. No line whatsoever with a handful of agents to choose from. Then spent about a minute organizing stuff for the security checkpoint, and went upstairs - very short line (but boy, they move slowly) - went up to AX lounge - opens at 5 - so I walked down to AM lounge - opens at 5, so back to AX, where a line was forming. Sat on the floor (in line) at about 4:40am. So, 20 minutes from plane to migracion to aduana to security to AX and AM and back to AX lounge entrances.
