Fascinating. Fewer than 40 on the flight, but everyone is bunched up at the front in aisles and windows and way in the back aisles and windows. One woman plopped down in a center and nobody is trying to sit next to her. Meanwhile the middle of the plane is empty. Gate agent, FA announced "take a whole row, we are empty" but folks didn't. All about getting off fast or back door boarding at BUR, I guess, or habits. No back door exit in OAK when we land.
Some academic should do a paper on this stuff.
