I'm flying from Brisbane to PM to Hoskins on Air Nuigini in July. I will have a backpack with most of my camera gear, a rollaboard with all essential dive gear as a carry on, and one small checked bag with clothes. Will this be ok as long as I'm under the total allotted weight limit or is there a limit on individual bags ? ( my backpack 18lbs, rollaboard 18lbs and checked back 15lbs) My other thought was to skip the checked clothing bag, and and wear layers. Just peel and leave as needed.
