Upgrading from premium economy award seat
Hi, novice here. I'm hoping to take a flight on a popular route in business class. It seems Asia Miles only releases seats in J a few days before the flight. If I book an award seat via Asia Miles points in premium economy can I then waitlist to upgrade via points to a business class seat? Or can you only upgrade from a paid premium economy seat?
I'm trying to avoid having premium economy also fill up and being left with only economy. Does this strategy make sense or are there other reasons why you recommend not doing this?
The route is JFK-JNB
