Grawr, and it turns out that i'm too late to book a cheap flight with Air Canada. And so far, only United Airlines seems not too retarded as far as prices and schedules.
... remind me to not try any planning-related thing or whatever early in the morning.
It turns out, there is no problem. I even wrote it myself, i got the 23 off! So i can just spend an extra day there easily. Whee.
But still, would be cool if i could have somewhere else to land in the USA on the 23, spend the day there, and head the rest of the way home on the 24.
