I am going on my first vacation to Australia beginning next week and am so excited about this trip. We will be flying from NY, to LA, to Sydney and onto Cairns before stop and will not see my checked luggage until Cairns. The Qantas website states that my carry-on cannot exceed 15 lbs. I bought a new lightweight carry-on with wheels as I am in my mid-60s and can't lug that shoulder bag as I used to, and, in reality, I'll be living out of my carry-on for the 30+ hour trip . I even bought a baggage scale to be sure I didn't exceed the allowance. Much to my horror, I busted 15 lbs packing carrying only 1 change of clothes and a very ightweight bathing suit (just in case my checked baggage get lost for awhile,) only my camera film - not my cameras (it can't go through baggage screening in USA), my sandals (have hard to fit feet and would have trouble replacing them) , my medication , and a toothbrush and, toothpaste! I want to bring other stuff for the long flights - reading material, a snack,.etc Has anyone had experience with Qantas strictly enforcing the 15lb allowance? Or is it more liberal about the weight if the carry-on meets its size requirements? Has anyone else had this problem? Thank you so much for your advise and comments.
