In another thread, it's noted, for United, "PN - Used for a Premier Instant Upgrade from B - Earnings will be the same as the underlying B booking class."
The Aegean site doesn't list "PN", but P and N are both listed as not accruing miles. Do I lose miles because I was upgraded?
Enter B-cl. That's the class you're earning miles according your ticket paid (you've also to enter your ticket-#).
PN-cl on UA is not the same as P-cl. The xN classes are AFAIK only used internally by UA...
