Companion policy
One companion traveling on a paid ticket on the same reservation as a Premier member is eligible for Complimentary Premier Upgrades on select flights, and may be confirmed with the same priority as the Premier member, even on the day of departure. If the companion is a Premier member, the upgrade will be processed according to the highest Premier status level in the reservation.
