I travel with my trusted TUMI orange carry-on roller, which I’ve had for years (another beloved, reliable keeper). I should replace it because it’s so old that the wheels only go in one direction, but I won’t yet. I don’t even own a larger suitcase because the Tumi expands, and I can stuff a lot in, like 5 bottles of wine! I have a pottery addiction, so I always take an extra foldable bag (my well-worn blue Longchamp tote to bring the goodies back as my carry-on. Lastly, I always travel with a cloth grocery tote bag too, which always come in handy. Light, washable, inexpensive and so practical, especially walking around in Europe, where plastic bags are verboten.
I take my Tumi plus extra bags to the destination, then stuff the expandable Tumi and check it in for the return flight. I carry the 2 totes on the plane. Works every time!
