I am an E50 on Flex W fare, should be 5 days ahead I think (currently 5.5 away from the trip). As mentioned, I was allowed to join the wait-list for the flight. The return flight which is currently 8+ days out says "Upgrades can only be requested within 8 days of departure." I don't recall seeing anything related to an 8-day time period posted on AC.com - has anyone else had experience with this or is it specific to this route perhaps?
