I expected to see it in the One Pass changes thread but its eluding me. I am trying to do a paid upgrade to first and online wants to charge me the change fee as does the customer service rep i spoke with.

The applicable change fee will be waived, but the most restrictive fare rules between your original fare and the new fare will apply to the new ticket. If we're ever confused about this over the phone, politely refer us to GG BUYUP.
