Possible tweaking of NA sector's
JFK-DFW-BOS-SFO-DFW-LAS-LAX is 8413 miles, with 1 LAS-LAX at 236 miles (poor SC's)
BOS-SFO-DFW-LAS-SAT-ORD-LAX is 9079 miles and all flights are over 1000 miles. Take Amtrak train NYC(JFK)-BOS 187 miles. SAT is better to go thru/visit than going to Dallas twice. Still the real miles are to ANC or SJU
