Regarding SAN-DFW: to each their own, but I can't imagine choosing to fly SAN-LAX-DFW to get a 763. It turns a three hour trip into five hours, starting with a regional jet followed by a shuttle bus ride from the Eagle terminal to T-4 at LAX. I would take either the MD80 or the 737 non-stop. If you end up in F on the MD-80, the seats on the right side of the plane have more pitch than the left side.
