My husband and I are travelling to Argentina in August, arriving into Beunos Aires Pistarini (EZE) at 10:50am. We will then have to transfer to the other airport Aeropark (AEP) to catch a LAN flight to Bariloche. How long is the transfer and what is the best way to do it? Is there a LAN lounge at AEP that QF Platinums can use?
