Delta Air Lines on Tuesday introduced a “simplified” boarding system: Passengers will be divided into eight categories, based on the type of ticket they bought.
Other carriers have tweaked boarding categories and methods in recent years. American Airlines last year introduced nine boarding groups to include its new bare-bones basic economy class. In September, United Airlines started boarding travelers in two lanes instead of five to prevent passengers from hovering near the gate for their group to be called.
