The side sleeve to attach to luggage is badly designed
"The bag overall is okay- the material is very high quality and looks rich. The design is thoughtful but in many ways not functional for long trips and multiple flights. I used my new bag from SAT to DFW to PHL to ZUR to LHR to DFW to sAT. - so tried it out. It is not compact. Does not balance well and becomes side heavy and top heavy even when not completely full. Hard to handle if you are a petite woman. I am 5’1 and 102 lbs"
