Audreylita, when you carry this Longchamps bag on a plane with your H bags in it do you also carry on another larger bag that you put in the overhead compartment ? ie Is this your allowed purse or tote in addition to a carry on bag or do airlines consider it your carry on?
I always have a purse, this is just my carry on. Last time I travelled I used a 35 cm kelly as my bag and it sustained a nasty scratch somewhere between the x-ray section and the plane. So the good bags get put in the carry on (I used a Nancy Gonzalez as my purse, it's pretty tough)
I do not put anything like this in overhead. I only carry on bags I can put under the seat in front of me. The thought of putting a birkin in a soft sided bag with the prospect of someones hard case carry on pressing up against it is beyond my level of comfort.
Also, the Le Pliage zipped closed, which is the identical size and style to the non-zipped version, was a bit short when zipped closed for the handles of the 30 cm birkin. Yes the bag did close but it pressed a bit on the handles which I wasn't thrilled with. A 35 cm would definitely need the zipper opened to accommodate its height.
