It’s really not a question about an upgrade, it’s a uestion about what fare class this is actually booked in. I have had 11 credits deducted and am on the wait list. My fare code on the ticket shows N which should be more upgrade credits plus a co-pay. If 11 credits have been deducted this is either a Latitude of Flex PY - I am going to assume it s the system saying Flexible PY and not Latitude.
