<p>I can't find any place that states what constitutes "duty-free" bags on planes. I have a backpack that has quite a few things in it, and I am also bringing carry-on luggage along with my laptop. Does a backpack constitute "duty-free"? Is there a weight limit for a duty-free bag? My airline does not have this information, and I can't find it anywhere online.</p>
<p>Yes, you can bring one carry-on luggage plus one personal item (i.e. a backpack). If it’s a pretty large carry-on bag, you can check it at the gate and they’ll put it in the back of the plane for you.</p>
<p>“duty free” usually refers to purchases made in the airport – you will not need to pay
customs duty on the exempted items. YOu get a duty free receipt at purchase.</p>
<p>watch the weight limits if you’re packing a lot. i almost went over on my luggage and if i had it would have been an extra $120</p>
<p>Duty is a tax paid on some international purchases. If you are flying within the U.S. (states) there is no duty. If you are returning to the states from some U.S. territories and foreign countries, there is duty charged. If you don’t have to go through customs, you don’t have to worry about duty (and you can’t shop at duty free stores.)</p>

<p>That’s what I thought as well. Little confused by the question.</p>
<p>OP, do you mean “duty free” as in the additional allowed carry-on that some airlines will accept? If so, they don’t weigh it but you should be able to carry it by yourself.</p>
<p>I couldn’t find a definition of “duty free” bags. If it is additional carry-on, then my question is answered, if not, solutions are still needed.</p>
<p>The term duty-free is usually only used when traveling between countries and purchasing something in the other country and bringing it back to the home country.</p>
<p>As for carrying on luggage: You can carry on luggage as long as it fits in the overheard compartment above the seats. Airlines also have a limit on how much of a liquid/gel item you can carry on.</p>
<p>Why aren’t you listening? If you’re not flying INTO the US from another country, there’s no duty on anything.</p>
