Hi folks. I'm trying to get a saver award from WAS (any airport) to CMB for my wife. She wants to travel leaving in early July and returning in late August which is other than around Chistmas the worst time to get frequent flier seats. I was able to get a ticket outbound. However, on the return it showed availability at the saver level but when I actually selected it, all but one leg of the trip was confirmed in economy including the longhaul leg from Tokyo to Toronto. I tried to see if I could get a one way award using Mileage Plus and then use my AA miles for the retrun. No dice as starnet blocking is in effect and the same seats Onpeass shows available are "not available" to the Phillipines call center person I spoke to at United.

So here's my question. If I book the existing itinerary and later on (it is really easy to check using Continental's website) business class becomes available would I have to pay the $75 to change from Y to J? each time a flight becomes available in J
