As a Korean American living in NYC - its been extremely hard to find Asiana/Korean Air Business Class redemption availability using partner miles (e.g. AF, AC and etc.). I have a gut feeling with the Asiana / Korean Air merger closing out soon they may not be releasing as much availability to partners. I know you asked for AMEX Points but I've been opening up personal and business cc for US Bank Korean Air card to get the miles necessary for KE J redemption using Skypass.
