In this particular guide, it is relevant to learn the size of the carry-on British Airways allows you to take on their flights. British Airways has rules that only one piece of cabin baggage is permitted and cannot exceed 56 x 45 x 25 cm (22 x 18 x 10 inches), including wheels and handles. Your carry-on baggage should fit into the size checker at the departure gate and its weight should not exceed 23kg (51lbs). A laptop bag or handbag, such items as food and drinks, and any other necessary items that you will require during the flight must be carried in a space found under the seat in front of you. Therefore, following the size and weight requirements of British Airways for a carry-on will make your journey through the airport enjoyable and you will not have to part with your luggage at the gate. As outlined by the handy carry-on guide of British Airways, this may help you avoid complications on any of your travels.
