Australia and New Zealand run the strictest cabin weight enforcement of any region, with Qantas, Virgin Australia, Jetstar and Air New Zealand all capping the overhead bag at 7 kg and weighing it at the gate. The Pacific island carriers add small aircraft rules on domestic legs, where a 5 kg cabin limit and a combined passenger and bag weight are normal.US travelers reach the region on long haul flights that carry a two bag allowance, then hit the domestic caps on the next leg. Every figure on these pages was read off the airline’s own site and dated.
