We are going to Australia in a couple of weeks and I have to so some flights alone with DD (will be 8m) when DH working. Was about to buy The two of us (girls) a double deck trolley/wheely bag (eurgh, but my existing bags too small and cheapy sports bags or rucksack so would be chaos w double packing)... However suddenly worried about pushing buggy and bag... What luggage do MNers recommend? I want two main compartments if at all possible. Thanks.
