Don't get me started... New captain, day after Christmas. Christmas day flight cancelled, so a bunch of angry pax from that. 4am YYC van, plane with no APU, -35C or something like that. Plane completely cold soaked with no winter protection kit installed. Chattering and shivering like crazy trying to get the hydraulic warmup done and went through several ground carts and 3 hours trying to get the plane warmed up. Couldn't start an engine at the gate until pushing because Canada and ground crew safety. Get plane warmed up, hey why's OO sitting there still? Weren't they supposed to leave 3 hrs ago? ... oh, the deice fluid is only rated to -29C. That's cool. More gate announcements. Only a few more hours until it's warm enough we're legal. Getting close now. Load the people... Push back... Deice. Bleed failure. Call MX. No, we can't do that. Nope, can't do that either. Okay. Okay. Logbook scribble. Holdover time? Whew, still good. Flow for Seattle. Wait for flow time. Take off.... Plane is finally warm and toasty but still teeth are still chattering like crazy, the whole leg. FO too. Realize I'm mildly hypothermic. "CA pls call when landing. Rest of crew is released. We have an assignment for you..." Get to Seattle about 1:30pm, call scheduling. "Captain, you're going to do a RDM turn." Nope, I'm fatigued. Absolutely done, thanks. Find another sucker. Go to the hotel, brew hot tea, take hot showers, still shivering like crazy but finally fall asleep for a well deserved nap. #justregionalthings
