US Airways Dividend Miles (Pre-2005 America West merger) - PHL-YYT no seats?

I wonder if you knowledgeable folks can help me. I contacted the Star Alliance desk at USAir for a flight from PHL to YYT (St. John's Newfoundland) on specific dates. Thinking this was an unusual flight request, I was surprised that they had no availability.

Now, I know next to nothing about these things. Is there anything else I can do? What are the odds that there might be some if I wait a week ( the trip is in two weeks)? Do people frequently reserve and then cancel when using FF miles?

Any helpl or insights you could provide would be greatly appreciated!

It's probably because you'll have to transfer to Air Canada, so either it's the US Air flight to Toronto / Montreal, or the connecting flight on some small RJ or turbo prop.

yyz-yyt is operated by an a320, yul-yyt on an a319. Ask where the availability problem is and try to route creatively. if phl-yyz-yyt isn't open, phl-us-iad-ua-yul-ac-yhz-ac-yyt might be.. though it would probably take you a full day of flying ;)

You could also try PHL US BOS AC YHZ AC YYT...

Depending on the time of year, reward seats to YYT can be rather tough to snag. In addition, Air Canada are downsizing its flights to CRJ-700s in the coming months, so seat should be even tighter. In my experience, flights stopping in Halifax have the most likely to have open reward seats, rather than the non-stops from Toronto or Montreal. Good luck.
