Having said that, trying to max out all 6 North America segments may not be as advantageous as trying to max out other parts of the world. BOS-LAX for example is shorter than DEL-TYO or DOH-DUB. If your goal is max BIS meiles, since you only get 16 segments in total, I'd make sure my Europe and Asia segments were optimized first since that can be 8 of your 16 plus the minimum of 3 intercontinental segments, you're already at 11.

Within North America, don't forget Central America counts and isn't subject to the transcon rule. Since you have to break up your transcons anyway, it would be more miles to fly to Costa Rica for example than DFW. AA at least seasonally flies JFK-LIR, though it's not the same season that AS's JFK-ANC operates, I think the only one that both AA and AS operate throughout the year (From JFK and AS's west coast hubs) is CUN, but it's still more distance than a transit in DFW.
