Intl Premium Plus - price difference
EWR to MXP flight.
I paid for economy for my daughter and I.
Used points to pay for my wife and son.
Looking at Premium Plus upgrades.
It is showing $389 for my wife and son. (XN fare)
But showing $558 for my daughter and I. (L fare)
Why is there such a difference?
I’m thinking about using miles to cover the $558 for my daughter and me, and cash for wife and son.
I’m worried that if I book 2 of the seats, could that drive the price up for the other 2 since it limits availability?
I’ll be Gold by the time we fly. That could help my daughter and me, but wife and son are on a different ticket from me. So likely no status. Not sure if that helps at all.
If premium plus doesn’t work out I’ll do economy plus using the 2 free upgrades from the credit card for wife and son. Then use my gold status to get economy plus during check in.
Appreciate any insight / strategy from this group!
