Yes, United Airlines checks boarding groups during the boarding process. Each passenger is assigned a boarding group based on fare class, seat type, and loyalty status. Your boarding group is clearly marked on your boarding pass. Gate agents call groups one by one, and they generally enforce the order by scanning boarding passes and asking passengers to wait if it’s not their turn. Attempting to board early without the correct group may result in being sent back. To ensure a smooth experience, listen for announcements and line up only when your group number is called.
