Best seat to sit in on a Southwest Airlines flight.
It is in the section of the plane with the statistically highest survivor rate.
It is in the part of the plane with the highest stability.
It is in a row that most people will not think to sit in.
It is close enough to the front to deplane within a reasonable amount of time (as in, before becoming frustrated with the people in front of you not moving quickly enough).
It is far enough to the back to be open even if you're at the beginning of the B boarding group.
And it is an aisle seat.
