Aircraft swap in the middle of the trip, run off the jet to the other gate. Did I mention it's a thirty minute turn? Get to the new gate, fight my way politely down the jetway full of boarding passengers, step into the cockpit whose previous captain KNOWS its a thirty minute turn and I find the seat full down, rudder pedals forward to the stops, armrest adjusters zeroed out full down and the headset unplugged, cord wrapped tightly around the ear pads tied in a knot and stowed in a bin. Thanks for nothing.
