Hi all,
trying to redeem a few flights on Aerolineas Argentinas and struggling getting Delta to price them out right.
Specifically:
1) airport change seems to cause the flights to price as two one ways
e..g, flight from Brazil to El Calafate (connecting in Buenos Aires) - international flight comes into international airport, local flights departs from local airport
2) long connection (14h) on select routes pricing the flights as two one ways
e.g., flight from El Calafate to Punta del Este (Uruguay) - system will only find availability if splitting the flights (total connection time ~14h), on other routes such a long connection time seems to be ok.

Any experience with this? Do i just have to get a good agent on the phone? I'm a PM if that helps.

Thanks!
