This meets carry on size regulations so it will work as a carry on. The bag that comes withit it tiny and not really very useful. I purchased this bag for it's color since most flyers have black luggage . It seems to be sturdy easy to pull along. I used to check my luggage but Delta charges $15.00 per bag each way , I have already given them mucho $$$ for my airfare and do not want to give them more :)
