Upgrading X to PE with the current promotion
Planning to take advantage of this eUp promo with an AP X booking into PY, with the ability to do so only at check-in.
If at OLCI the option to use eUpgrades for PY does not appear, can I request this with a check-in agent on the day of the flight? My current understanding is that, yes, I can do this with a check-in agent if it's not offered at OLCI.
