And, late arriving...

Apparently the plane was delayed -- and arrived at a domestic gate and so needed to be towed to an international gate (at YYZ). Then, that delay meant one of the crew needed to be replaced, giving another delay. So, all in, about 1:45 late into Seattle.

Then, Avis has rented my car to someone else, so another delay there.

Also, SeaTac does not have the clearest signage of many airports I've been through. (And, I've been through a bunch of airports.)
