By this point, everyone knows there are limits to the size of liquid containers you can bring on an airplane inside your carry-on bag (3.4 ounces or smaller, all must fit inside a one-quart bag). But what about in your checked baggage? How much liquid and how big of a bottle or other container can you take on a plane in your checked bags?
The answer, thankfully, is that there is no limit. You can take as much liquid as you want overall, and the size of your bottles or other liquid containers is not limited. So you can feel free to pack full-size shampoo, sunscreen, toothpaste, hair gel or aerosol hairspray, beverages, whatever, in your checked bags. This is true across airlines — doesn’t matter if you are flying Delta, United, American, Southwest, etc., because all airlines follow the rules set by the TSA (Transportation Security Administration).
However, you obviously are going to want to set some sort of limits personally, because too much liquid will weigh down your bags and might make a suitcase heavy enough that you’ll have to pay an extra checked baggage fee for oversized luggage. (You’d really have to carry a LOT of liquid, though.)
