Award inventory codes
 

Does anyone know what inventory codes (D class? I class?) are used for business class awards on various SkyTeam airlines, such as AF, KE, AZ? I know that KL and NW use D class.

AF is O.
AM is C.
DL is R for FC US domestic; O for BusinessElite.
KE is D.

I actually don't know what AZ uses. Which is quite embarassing given I'm an AZ elite :D

I think biz awards on OK are D-class.

For what it's worth, AZ definitely isn't D (which is slightly discount business) or C (which is full-fare business) or Z (which is heavily discounted business), so I bet it's O.

Here is what I've compiled so far ... please advise if any changes needed:

AZ Awards:
Economy: U class
Business: Z class

KE Awards:
Economy: U class
Business: D class
First: A class

KL and NW and MH (not SkyTeam) travel:
Economy: W class (on KL, at least)
Domestic First: A class
Int'l Business: D class

DL Awards:
Y to C upgrade: Z class
Int'l Business: O class
Domestic First: R class

AF Awards:
Economy: X class
Business: O class
First: A class

AM travel:
Business: C class

CO travel:
Dom First/Intl Business: E class
