I'm a Platinum traveling with 4 award tickets to ITO (Hilo, HI) from LAX, all on the same PNR. This flight is wide open in 1st and coach+ two months out. I'm assuming that while the KOA (Kona) flight would have a lot of elites that the ITO flight will be filled mostly with local's (or volcano watchers?). Anyone know of the paid upgrade cost and or likelihood on LAX-ITO flights to buy up into 1st? I'm assuming that I won't be offered an online upgrade because these are award mileage tickets and there are 4 pax.
