Hi, -- I'm seeking some help from the collective brain trust here. I'm looking to maximize the mileage in my North American segments on my next DONE3. I'll have all six flights available, and the itinerary must start at BOS and end at LAX. (If you're curious, the flight in will be NRT-BOS and the flight out will be LAX-DOH.) No other restrictions with regard to cities. It will be in the second half of January, and my usual DFW/ANC flights don't operate at that time. I credit to QRPC, so AA coded is better than AS. The best I've been able to come up with so far is 12,234 on BOS-DFW-SJU-ORD-LAX-ANC-LAX (calculated using MILECALC), but that itinerary bears the usual weather risk connecting at ORD in January.
