More than likely they will trying 12-15 kg's.And who is going to police this at the gate !!
Once onboard and all the O/head lockers are full and the GS demanding push-back,guess who's left with the problem.The CC who else.
I can see angry punters and delays due to offloaded baggage ahead.
More delays will be inevitiable, but the "SPIN" sounds good.
