You can eUpgrade to CUN. Sun destinations are allowed with no add-on.
Just international dests require an add-on.
Incorrect, OP has booked this through ACV so only able to upgrade if 75/100K.
OP, was your first segment also booked through ACV? ACV buys seats from AC and therefore has many more restrictions than a mainline ticket since your fare is consolidated with a vacation package. I suspect you will not be able to upgrade your first leg. But you could certainly try when you check-in at the airport. I would not get your hopes up though.
Your second segment to CUN will not be eligible for upgrade, but you will be on rouge so you won't be missing much.
