I will depart EZE on the 11:40 p.m. flight on a Sunday in January. I'll be in F. First, I am considering an Iguassu Falls-AEP Lan Argentina flight arriving at 7:45 p.m. that same day - will only have carryons. Various internet sources indicate this is may be a bit aggressive. Was wondering if (1) the fact that it is a Sunday night and (2) I will have access to whatever benefits of being in F (checkin, and perhaps - but I do not know - expedited exit customs, security, etc.) will mitigate things such that I can expose myself to the risks). I'd appreciate hearing of others' relevant experiences.
