Carry On Bag Basics
A carry on bag is a small suitcase or backpack that fits in the overhead bin or under the seat. Most airlines limit it to about 22 x 14 x 9 inches and 15–22 lbs. Check your airline’s size and weight rules before you pack to avoid gate checks or fees.
Essential Documents and Tech
Always carry your ID, boarding pass, passport if traveling internationally, and any required visas. Keep medications, chargers, and a power bank in your bag. Electronics like phones, tablets, and laptops must be removed for security screening, so pack them where they are easy to access.
Comfort and Personal Items
Pack a change of clothes, toiletries in travel sizes, and any daily medications. Include a travel pillow, eye mask, snacks, and an empty water bottle to fill after security. A light sweater or blanket layer helps with temperature changes on the flight.
