I recently booked trip for 2 on CO from EWR to PUJ and the class was "S". If I look at my reservation under my Onepass account and go to the Upgrade Reservation online it shows both myself and spouse. For upgrade to "Z" class it says each leg would be 15,000 miles and then there is a seperate check box for entire trip | 15,000 miles. Not sure what that means or how that works. I almost look at that as saying for roundtrip upgrade to business class it would be 15,000. Now for the real stupid question. Would that be just for myself or both my spouse and myself? The way it reads or looks it shows both of our names checked and listing those miles. I have never used any miles before and only have 55K to burn so thought this would be a nice time since I really don't travel much.

Thanks in advance!
