With my name, I know I should fly CO, but NW also works. Upgrade question. If there are multiple passengers linked to a platinum's ticket, does NW automatically upgrade the platinum (if seats are available)? I know CO does not, but am not sure about NW.</font>
For multiple reservations in the same record, upgrade is done based on the lowest level. If you have silver and plat in the same rercord, upgrade will process at silver EUA window unless you split the records.
