The whole purpose of a laptop is its portability, and a plan is a common place for travelers to work. Tray tables in standard airline flights can generally accommodate laptops, including 15-inch models. Remember, you will likely have limited space to work, so you may not have room for additional accessories, including a mouse. To ensure a smooth experience, check with the airline or consult their website to see if they provide specific dimensions or guidelines for electronics usage on your flight. We also recommend stowing your laptop in a well-padded case or bag when you travel for protection.
