I'm surprised no one mentioned the CRJ for fave short haul equipment. I love 'em, and I give Delta Connection the nod for flying them. They put United Shuttle's 737 fleet to shame, which BTW are my most hated aircraft.
FC fave: 747 upper deck and A320.
Fave seat of all time: 747 jump seat on my 10th birthday. (Sigh.)
