Hi!

I am relatively new to travel hacking, and have been trying to figure out how to know what fare class code to search for, in terms of economy or (of more interest to me) business class bookings using partner miles.

I am posting this here, as (aside from United) AA metal might be the most interesting for me. With no way to transfer Amex or Chase points to AA, partner booking is the way

From what I've read so far, it seems that fare class "I" seems to be the one to search for in terms of business class fares available for partner airline booking-- is this correct for AA? I've been told to look for Saaver fares (are those "I"?).

As a followup, I'd also like to ask if this site (or any other travel site, if not FT) has a primer on fare classes? I am out of my element here

Thanks in advance for any advice!
