Family of 4 going on hols next week. Cases have always averaged out at less than 22kg each in the past (usually a couple of cases over; a couple of cases under weight), but our girls now late teens and worrying this might no longer be the case! If we pay for one additional 22kg case (£56 return) could that allowance be shared across our original 4 cases (as long as none weigh over 32kgs) or does it have to be an actual extra case? Hope that makes sense!
