BTW, here is the complete list of IATA-recommended codes:

Code:
R    Supersonic
P    First Class Premium
F    First Class
A    First Class Discounted

J    Business Class Premium
C    Business Class
D    Business Class Discounted
I    Business Class Discounted
Z    Business Class Discounted

W    Economy/Coach Premium
S    Economy/Coach
Y    Economy/Coach
B    Economy/Coach Discounted
H    Economy/Coach Discounted
K    Economy/Coach Discounted
L    Economy/Coach Discounted
M    Economy/Coach Discounted
N    Economy/Coach Discounted
Q    Economy/Coach Discounted
T    Economy/Coach Discounted
V    Economy/Coach Discounted
X    Economy/Coach Discounted
