I have a slightly complicated question about an RU on Air New Zealand (have read the other thread but it is now locked). I'm flying home from work in HKG tomorrow and have requested a recognition upgrade from PE to Business (requested it last week 7ish days ago before my flight over). After my flight over to HKG last week my airpoints status was upgraded to gold and is now active, which should hopefully bump me a little up the queue for upgrades.
Since its within 24 hours of the flight back, and online check in is open, I was wondering if it is better to check in now, or at the airport for the best chance of the upgrade going through (I've had limited success using RUs in the past). I've heard (from other GZ threads) that its mostly dependant on spare seats at time of check-in but not really sure.
Advice appreciated. Hoping to be able to have a good nap on the way home.
