Question on when a reservation needs to be "Synced"
Hi folks:
I know SHARES can be a bit difficult when a reservation no longer matches a ticket.
So my question is...when does a reservation need to be "synced"? I've heard this is required, for example, if a GPU clears before the 24 hour mark. Is this true?
And also..what exactly happens during the sync? Is the ticket actually re-issued? Or is it just syncronized with the reservation? Can someone explain what actually happens?
I'm concerned because I have an upcoming itinerary where I"ve managed to get an upgrade on Lufthansa on my return flight using a Star Alliance upgrade.
I have initial segments on UA on this same itinerary that I'm also trying to upgrade with a GPU. The ticket is a UA ticket.
I don't want to lose my Star Alliance Upgrade on LH and that will absolutely happen if the ticket has to get reissued.
Thoughts?
