I just did the centimeter to inches conversion. The carry on bag size is 55x40x20 centimeters which equals 19x15x7 ! That seems so small to me, like a high school student's back-pack size! We are trying to not check any luggage at all. We're a family of four, traveling to 7 cities over a month, with only carry-on luggage (and plans to do laundry often). Is this possible? Am I crazy?
I was looking on many sites such as rei and campmor, looking for appropriately sized bags. slim pickings! Suggestions on which one to buy?
