I was searching this forum for packing tips awhile back and wrote down a tip for a soft sided rolling carry on duffel bag. It was an Olympia 22" 8 pocket model. I just went to purchase 4 for my family and am seeing complaints on Amazon that it's over-sized for a carry on. Have any of you had that problem? I looked up the dimensions and yep...it's over the limit by 3 inches. What others do you recommend, I don't think I want to take chances that they force me to check 4 bags in at $25/piece each way.
