Hi, quick question. I'm booked on a Jetblue flight, SEA->BOS at 11pm (on a Tuesday fwiw). I'll be coming from Vancouver that day, and there's an Air Canada flight that would land at Seatac at 9:20pm. With 1h40m between flights, is there any reason to be concerned? I think I can pre-clear customs in Vancouver, so that shouldn't be an issue.

Just my planning paranoia taking hold - of course, if I miss my flight it just means I can't go to work the next day, which...hmm.

Thanks!
