I am flying BA, LHR to SEA. The flight is set to arrive at 15:55, there is a 16:25 flight SEA to YEG on Alaska Airlines. Is there any chance of making this connection? I am not familiar with the SEA airport at all, not the relationship between BA and Alaska. Would my luggage be routed directly, or would I have to claim it in SEA, and re-check it? Would I have to go through customs in SEA before departing again to Canada? I am guessing that this connection is not "do-able", but would love some imput. The next flight does not leave until the next day. . .
