“Most passengers know their large carry-on items go in the overhead bin wheels first. Jackets and coats go on top of the bag. Smaller bags go under the seat.” Wheels first makes it easier for passengers to grab the bag when leaving, making getting off the plane faster, which is something everyone wants.

On a standard commercial flight, your carry-on bag (the larger of your two allowed items) must be stored in the overhead bin located directly above the seats. Most airlines have specific size limits for these bags—typically around 22 x 14 x 9 inches—to ensure they fit within the bin's depth. When placing your bag in the bin, it is standard etiquette to place it "wheels-first" or "sideways" as indicated by the diagrams on the bin door to maximize space for other passengers. Your smaller "personal item" (like a purse, laptop bag, or small backpack) must be stored under the seat in front of you. This ensures that the floor area is clear for your own feet and that the aisle remains unobstructed for safety. If you are sitting in a bulkhead seat (the very first row of a section with a wall in front), you are not allowed to have any items on the floor during takeoff and landing; in this specific case, both your carry-on and your personal item must go in the overhead bin. If the overhead bins become full before you board, flight attendants may "gate-check" your carry-on bag, meaning it will be placed in the cargo hold for the duration of the flight at no extra charge.
