Therefore, without wanting to suggest this is a definitive response, my take is that it is an 'all or no-one' situation.
Thanks for the insight. That makes sense but leads me to more questions as I try to understand how this works.
1.The app and the web page state that an auto upgrade will only be processed between 30 days and 72 hours before a flight. Does this mean that if upgrades become available prior to the 30 days you could miss out to someone who hadn’t enabled auto upgrade?
2. It also states, as you said, that all passengers on the booking will be upgraded and miles will be deducted from your account. In my case my wife and I both have enough miles for an individual upgrade but neither of us have enough miles for the 2 upgrades. What might happen in this case? Is the system smart enough to deduct the miles from each passengers account rather than trying to deduct them all from one account?
