even after almost 45 yrs of flying I still like taking photos of plans at Airports... (AEP) Aeroparque "Jorge Newbery" , for my domestic flights to USH and IGR (Iguazu Falls. This was not our flight, even though we had a jet bridge, we were bussed to the aircraft on the tarmac. Don't expect flight info at each gate, even though there may be monitors, no such info seems to be ever displayed. You need to know enough Spanish to understand when your flight number is called. You may need to wait before security to see what gate is posted for your flight as it's not known typically when you check in.

on the food box on Aerolineas Argentinas flights they were using stamps like this of type of aircraft they have used.

the food box on Aerolineas Argentinas flights, as experienced on 4 domestic flights. The meat flavoring of the crackers was "different". Bust is was nice to experience something from all the US Airlines long forgotten past....
