Hi, sorry if this question is not appropriate in this thread but could not find any better from my quick search...
We are a family of 4 which will fly JFK-SXM-JFK in July, we are booked in T and V.
I am a Star Alliance Gold, and just got matched/challenged to Delta Gold, mainly to benefit from the baggage waiver.
I also noticed the complimentary upgrade perks and have some questions:
* What are the chances of upgrade to FC for a Gold member, i believe this route we are flying might not have many business/frequent travellers. As of now 1/20 FC is booked.
* If a upgrade goes through would it just be myself getting upgraded, 1 companion or the whole family on the same booking? (Just me would not be popular/ not an option

)
*my spouse is star alliance silver, might try to match her to delta silver, is it likely for a silver to get an FC upgrade?
