The airplane liquid limit can be a bit tricky to navigate! Generally, you can carry liquids in containers of 3.4 ounces (100 milliliters) or less in your carry-on, all placed in a quart-sized, clear zip-top bag. Checking larger liquids in your luggage is usually fine. Do you have a specific trip coming up, or are you just planning ahead for travel? I'd be happy to help with any travel-related questions you might have!
