We have periodically adjusted delta new boarding procedures to improve efficiency and reduce boarding times. In recent years, Delta has implemented more structured boarding procedures that emphasize clarity and organization. For example, passengers in premium cabins, such as Delta One and First Class, still board first, followed by Medallion and Sky Priority members. Delta has also experimented with different boarding methods, including alternating between window and aisle seat passengers to reduce crowding in the aisle. These new procedures aim to minimize confusion, improve boarding speed, and provide a better overall experience for passengers.
