Carry-On Basics

Your carry-on bag is your travel companion, so it’s crucial to pack it wisely. Here are some fundamental guidelines:

Size and Weight: Most airlines have specific size and weight limits for carry-on bags. Check with your airline before packing.

Sharp Objects: Items like scissors, knives, and razor blades must be placed in checked baggage or left at home.

What You Can Bring

Water Bottles: Yes, you can bring an empty water bottle through security and fill it up once you’re past the checkpoint. Some airports even have water-filling stations.

Electronics: Laptops, smartphones, tablets, and e-readers are generally allowed in your carry-on. Be prepared to remove them during security screening.
