Boeing 737-800 (N848NN)

"Gentlemen, On Your Mark, Get Set, GO!"
In this dawn-light photo of a "Boeing 738 Jet Class" "race," (obviously, I'm j/k -- grin) the 6 AM race is in progress as American's N848NN, southbound on Taxiway Alpha, is in the lead versus Southwest's N8631A, southbound on Taxiway Bravo. The AAL B738 is just about to cross the "finish line" (the centerline of Runway 7-25); however, despite being the "winner,' once the two 738s got to the ends of their respective taxiways, the American jet had to wait so that the Southwest flight could depart on 34L first. .. 0/103/@6
