I know there has been a lot of talks on the BA board about this, but when I went to LHR 2 weeks ago the F Class agent can't give me a definite answer so I want to clarify this.

On a DONE4 you can check in 2 pieces @ 32Kgs each on the following airlines:

1) CX
2) QF
3) JL
4) IB
5) AY
6) ML
7) RJ

However on BA what is the deal
3 Bags @ 23kgs or 2 Pieces @ 32kgs each??

On AA I know for domestic they have a stupid rule regarding some weight restriction, but I never really got asked to pay the excess as I will be in F Class anyway for US Domestic (even if they asked, isn't it a small charge anyway?)
