My wife and I are planning several trips this year, the main one being to Argentina in Nov/Dec. Based on my research the best options are probably American Airlines to get to Argentina and then use oneworld partner LAN while in Argentina OR Delta to get to Argentina and fly Skyteam partner Aerolíneas Argentinas domestically while we are there. That said, my wife and I both just unsuccessfully tried the 2 browser trick (I was approved for the Amex and she was approved for the Visa) with 50,000 miles. I was thinking about the following, based on where I want to travel this year if there are any other recommendations I’d love the input. Citi AAdvantage Amex - Been approved and waiting for the card with 50K sign on bonus Chase British Airways Visa – If I get this card, can I use the miles to book trips on LAN while in Argentina? American Express Premier Reward Gold – Not sure if this will help with my trip but it is such a good deal I should probably jump on it What else will help me on this trip?
