I have been obtaining an award ticket for my wife (in WBC) to join me on trips to CPT, and for the last two years I have only been able to use Rulebuster awards (240,000) to get from the U.S. to CPT, even though I start looking 330 days in advance and have flexible dates! When I asked today (after failing to find any routings via AMS-CPT) whether the EZE connection is possible, the agent could not find anything. I will try again, as one should always call back after being told that something is impossible... But it may be that this no longer an option.
