Thanks!
So as a sample, I chose tomorrow, Sunday nights 1115pm flight from LAS to JFK and chose business class "D" and then on the next page chose fare rules and it said "Fare Code - YA00UPNQ"
Another fare rule says "Fare Code - MA07UPNP"
Does that mean its a "Y" and "M" fare automatically upgraded?
If it said "J" or something to that effect in the fare rules it means there is no upgrades available, right?
