See again the example I posted above. With an AA domestic flight as the first sector, AA's domestic 0kg allowance becomes the allowance for the entire ticket - regardless of the fact that AA have an actual baggage allowance for international trips [so the argument above, that JU's allowance of a type for a type flight that is not actually appearing in the ticket - the JU TATL 2*23kg allowance - should apply, falls down], and regardless of the fact that the JL international sectors in the example would have a 2*23kg allowance themselves...if only there hadn't been this AA domestic sector at the beginning, pushing its allowance onto all subsequent sectors via this "FMC" rule.


0kg and a $25 bag fee applies across the entire ticket, as this is the allowance attributed by the "first marketing carrier" to the first sector of the ticket.
