Seems like there's a lot out there on EZE-AEP transfers but to avoid an airport change I'm looking at a LIM - EZE - REL. international to domestic transfer arrive 5am, depart 7:35 all on Aerolineas Argentinas. I've got an award ticket for LIM-EZE but availability didn't extend to Trelew so I'm looking at a purchased fare and separate reservations. Without looking I'd figure pretty good on-time performance for the overnight LIM-EZE??? Will be doing my very best to have carry-on only but maybe not. So is that enough time for customs, immigration, check-in, security? The 2.5 hours is a somewhat tighter than I'd like but then I've never been there so don't really know if thats justified or not.

The other option would be a transfer to AEP with a departure at least 5 hours after arrival .
