Question: looking at a one way cash itinerary for myself and 3 of my family members. I purchased the E+ bundle for the itinerary which consists of two legs.
Down the line if I see a good buy up offer Y to J on one or both legs, will the E+ bundle price paid be refunded? What if I take the upgrade on only one of the two legs. How does UA determine how much of the bundle price gets refunded?
