@mpkossen : you are right about not more XP earning with a paid upgrade. About more miles, this would be correct if the flight is credited as per the new rule (based on fare + extras). But here, a LGA-YUL flight is very likely under DL code, so the old rule applies (based on distance and booking class). And in the old rule, a paid upgrade was not giving more miles (miles were earned as per the booked fare class), unless benefiting from a system glitch.

Yes, but in that case, we don’t call that a paid upgrade. You just pay a fare difference to change your Y ticket into a J one (like if you had purchased a J ticket from the beginning), and then you earn the XPs of J.

That’s probably where the confusion comes from and it seems to be, at the end of the day, a problem with terminology.

U.S. airlines often offer you, when you access your reservations/future trips the option to “upgrade” to the next cabin. In that occurrence, the upgrade is not so much a promotional seat upgrade like at check-in, but essentially consist in paying the fare difference between the initially puchased fare class and the immediately available fare class in the next cabin. As pointed out, everything happens as if you were paying J in the first place.

The “upgrade” I purchased was really cheap because my coach fare class was already high.

I will call DL later on today and clarify with them what type of fare class I am officially in now (my reservation shows ‘A’ and ‘G’, which are typically domestic First fare classes). I will get back to you.

Thanks. I am definitely interested as I have this case during the summer (personal trip domestic flight with DL booked in Y but purchased a “paid upgrade” to F for about $85)
