I have a OW award flight booked for February:

ORD-NRT-HKG-MEL-SYD-LAX-ORD

I booked in first class. The ORD - NRT segment was already in U because there was no F availability. I was ok with that because it was going to be my first time in the upper deck on a 747.

Since then, the equipment was changed to a 777. Still in Business. Then the HKG-MEL flight was also changed from a 3-class 747 to a 2-class A-330, so I was downgraded from first to business.

At this point, I only have the NRT-HKG and SYD-LAX-ORD left in first class. It's starting to look less and less worth the extra 80k miles for 1st.

Do I have a chance at all of moving the entire itinerary to business and getting my 80k back?
