And that's before they change the flight on you.Also checked Kamloops flight from here in DC area out of curiosity.
Requires Air Canada with 2 stops, most with some combo of Toronto, Ottowa, Montreal, Calgary, or Vancouver. At least 10.5 hours and most options 1-3 hours longer.
Flying to Kelowna gives you some 1-stop routes (the return to DC is faster, but going out, the 2 stop routes are faster). But you have a nearly 3 hour drive to the resort then.
REALLY getting tired of having every carefully cherry picked nonstop or one stop flight turned into a three leg, fourteen hour continent-circling shit show by the airline a month after I book it. As you were.
