Flying next Jan ticketed using DL miles.

1st flight is AR 1873 FTE to EZE arr EZE 8:21 PM
2nd flight is AR 1140 EZE to FCO dep EZE 10:35 PM
...and then 3rd flight to Asia from FCO with a 6hr+ connection in FCO

All 3 flights on the same DL issued ticket.

I assume a 2 hour 14 min connection is sufficient in EZE (Domestic - Int'l) all on AR and all on the same ticket? It'll be a Monday night (so not the sporadic horrendous Sunday night immigration crush).

Never done this type of connection before so not sure if we are able to head directly to Immigration upon arrival from FTE or if we have to exit security and then re-enter with the other teeming masses. Not sure if we will be checking bags but I imagine they will be checked through at FTE itself.

If something happens at FTE or EZE, I also imagine AR will have to re-protect all the way to our final destination in Asia since all 3 flights are on the same ticket.

There is an earlier flight FTE to AEP arr AEP 6:06 PM but we'll have to run across town if we take that one so not sure that adds much to the equation.
