Hi!
I'm booked to fly NCL-DXB in December.
This route received a metal upgrade on 1st Sept to 777-300ER 2class.
I'm trying to book an upgrade with points but when I click on services by flight it shows a 777-300ER 3class!

My questions are-

1- does this mean that there will be less business upgrade availability?

2- will they still be lie-flat seats, or are they likely to replace with an older aircraft?

I note that there is no availability for 1st class to purchase on this flight so this suggests that this could change back to a 2class?
FYI seat guru also shows this flight as a 3class.

Any info gladly appreciated.
