Oh yeah? You can't one up this. My luggage case fits in my wife's purse and that's when my luggage is for a two week trip! Closed of course. When I open my case, it expands to the size of the room. I just love those air-removing plastic baggies.This has not been my experience. Every time I've replaced my luggage the new version of the same piece was always smaller than before because the airline rules had changed and become more restrictive. The largest universally accepted no fee luggage size is now so tiny you can barely fit a weekend's worth of clothes if you're lucky.
My roll-a-board luggage fits on the shelf at the top of the steps. It can also fit along the bar of the open-closet version.
