Hello: this is my first time posting in this forum. I have done some perusal here but cannot find recent answers. Therefore, I am posting my questions here:

1. I used the online booking tool to try to seek an award ticket from the US west coast to HKG. However, all the results shown are in Econ. ==> How do I find Biz class inventory? The other *A account is United, which shows all sorts of inventory, but I don't know which is applicable to Aegean.

2. I have not dealt with Aegean phone agents before but expect them to not be the most customer-oriented. How should I guide them to help me find suitable inventory?

3. What are the change and cancellation policies of these award tickets? With Covid being a wildcard in that region of the world, I need flexibility.

I have purchased Aegean miles but have not done any redemption before. I am currently a Silver member, if this means anything at all. Thank you very much for your time and help.
