Priority Boarding is a service offered by airlines that allows certain passengers to board the aircraft before others. This typically includes first-class and business-class travelers, as well as frequent flyers and those who have purchased priority boarding as an add-on. The goal is to streamline the boarding process and provide a more comfortable experience for those who pay for the privilege. Passengers with priority boarding can access the plane earlier, giving them more time to settle in and store their luggage. This can help reduce congestion in the aisles and make the boarding process quicker for everyone.
