But IATA does not define the weight limit per piece, which is where the variation comes into play. yes, 3 pieces is more than 2 pieces, but when my ticket says 2PC for a DONE4, QF could happily carry the example 1x23kg + 1x28kg, while BA will want me to either repack it into 3 bags or charge an excess because 1 bag is more than 23kg.
I can see how a passenger at the check-in counter may argue that for their situation, the QF 2 piece allowance is more generous than the BA 3 piece allowance. So does the BA check-in agent have any discretion to interpret the words "most generous" to be able to apply to the weight restriction part of the policy or must it always be applied to the number of pieces part of the policy.
As far as I am concerned the baggage allowance policy is a combination of number of pieces and weight limit per piece. Separation of number or pieces and weight does not make sence, its the combination that applies. So for a DONE4 fare BA's baggage allowance policy is 3 pieces where no single piece exceeds 23kg. QF's policy for the same ticket is 2 pieces where no single piece exceeds 32kg. As the passenger, I would like to be able to choose which of those is more generous to me at the time of check-in with BA.
