As I mentioned earlier, there's a LOT of J availability on ZRH/AMS-USA.

The problem is that right now I don't think you're going to be able to book anything given the computer problems.... maybe later today? I'd try and stay off the phones unless it was completely urgent (long long wait times with lots of inconvenienced travelers). A vacation for a ways out that you need to change airport and award types for probably is not terribly urgent...
