The majority of travelers are assigned boarding positions in Alaska Airlines boarding groups B through E. Group B typically includes passengers seated toward the front of the Main Cabin or those who have purchased a premium seat. Group C generally includes those seated in the middle of the aircraft, while Group D covers passengers toward the rear. Finally, Group E is often reserved for passengers with Saver fares, Alaska's lowest fare class, which does not allow seat selection until check-in. By assigning groups in this way, the airline reduces bottlenecks and ensures that the boarding experience flows as smoothly as possible.
