I just red in AA.com the following:

For flights to international destinations

2 pieces checked and one carry-on
Please note that one carry-on personal item (see "Carry-on Allowance") does not count toward the free bag allowance.

The size limitation of your luggage is calculated by adding the total outside dimensions of each bag, that is, length + width + height.

Two checked bags at 62 in/157 cm each
One carry-on bag at 45 in/114 cm
Tickets Issued before March 1, 2005
The maximum weight per checked bag is 70 lbs/32 kgs.

Tickets Issued on or after March 1, 2005
The maximum weight per checked bag is 50 lbs/23 kgs

Bags checked to/from Japan will initially be exempt from the new maximum bag weight of 50lbs/23kg pending approval from the Japanese government. The maximum free bag weight for checked bags to/from Japan will continue to be 70lbs/32kg until further notice.


So is the new baggage alloawance for XONEX = 23kg X 2? or still 32Kg X2?
