Why do they not have a closed, oblong box rather than the 'frame' one? I, sadly, think I know why.....
We have a rigid cabin bag which we were planning on taking to the Med in 5 weeks time. 3 weeks ago I lent it to my mother to take on a RA flight to Munich. She kept it just under the 10kg and had no trouble with it- but I don't know if it was put in a bag measurer or not!; however, DH measured it yesterday and it's 2cms too thick. I so want to be able to load it up and test it rather than stress the whole time through the airports. We really do have a tight luggage allowance and are loathe to go out and buy another cabin bag that could just as easily 'fail' (if it bulges out of the 'frame' at all).
Any ideas?
