In post #3, the poster noted: "It's of course based on what you
paid."
I'm confused, especially if I'm flying on a DL Vacation package, where the price I
paid is not known to DL [which is why MQDs are Distance based for DL Vacs.]
I was talking about the new flight that you might change to. Not your existing flight booked with DL Vacations. I I have no clue how DL Vacations works, I have never used them nor do I ever plan to.
