Which one should I park at for ride to dfw airport -American Airlines on Saturday by 1:30pm 12/22 and returning 12/30 Sunday approx. 6pm ? I will be coming from West,Tx. 76691 on I-35 to park at Spot & catch ride at American airlines

Have a look, but even if you park at different spot, they have a very good shuttle service which will take you to whatever terminal you want to go. Same applies while coming back.

If you are arriving at DFW on the north side go with North. If arriving from the south side, go with South.

I always park at North but any of the 3 will work for you. North is farther away from airport
