I know that when you are purchasing an Economy Plus seat or upgrade to First, the price of this also counts towards your PQP earning. However, when purchasing a ticket for multiple people and only one Economy Plus seat is purchased upon booking (e.g. the other travelers get Economy Plus for free due to status), who ears the PQPs? Is it the person that books the flight or the person that is actually sitting in the purchased seat?
How are the PQPs assigned (assuming one ticket) when purchasing an upgrade to First? For example, two out of four people want to pay for an upgrade to First, while the other two are happy to sit in the E+ seats behind those in First.
