Assign one side heads and the other tails and flip a coin.
Currently AA2046 is the DFW-SJC-DFW rotation and AA2165 is a MCO-MIA flight. Given AA's love for changing flight numbers and times (to reset DOT reporting on flight reliability?), I would guess that AA2165 has more chance of sticking.
It looks like the double up happens starting January 8th, but in March the 2046 flight changes to a more reasonable 12:14pm departure (so nearly 2 hours apart).
