I would like to fly from JFK to LHR next May on Virgin Atlantic. I'd like to book my flight now, as the folks who own the B&B where I usually stay won't accept a reservation until I have a plane ticket (apparently, people have totally forgotten they made reservations, etc. so this is the new policy). I recently got a new credit card to earn 75K points in the first 90 days provided I spend a certain amount of money. I'm about halfway through the spending part. I thought I would book a Premium seat, then upgrade to Upper Class when I get my new points.
I've been looking over this table that explains how many points you need to upgrade. I'm a little confused. Why does it take so many points to upgrade from Premium to Upper Class, and so few to do it from Economy Classic?
Am I missing something important here? I've never upgraded before so I could use some advice from more experienced travelers. Thank you!
