Hello everyone. Could use some guidance from the experts on this board. Here's my situation: I already have a flight booked from EZE back to the US on Delta. I'm in Mendoza and am shopping for my plane ticket to BA to make this connection. My question is this: If I book my flight on Aerolineas (part of SkyTeam, as is Delta) into EZE, can I clear immigration and customs in MDZ and NOT have to check in all over again in BA, or do I have to collect my luggage and start the process over again? When I've flown from Arg to US through Chile, I didn't have to do anything at SCL, but I also flew on LAN.
I'd love to have more time in MDZ, rather than flying into AEP and then trekking across BA to get to EZE. Would love to know if others have done this. Thanks so much!
