Having an infant and the other half travelling often internationally I can tell you this new change is extremely hard and will only affect room in the cabin - there is a no way I'm paying extra...
So instead of checking 3 small bags we will now as prescribed check one bag but, we will carry on: 3 carry on bags, 2 nappy bags, stroller from Qantas, laptop bag, coat, and reading material, plus some shopping. Now that should take up the whole overhead locker I wonder how anyone else will fit theirs in - I can't understand how 1 x32kg bag is better than 3x10kg bags - are they really bulking out the hold??
Hmm virgin, Malaysian, airnz, Singapore, emirates, erm everyone Qantas say they can't compete against let us take the required items in a suitable manner - wonder who we'll be flying with from now on...
