Hi, -- I would be grateful for any thoughts/suggestions on an itinerary that I will likely start on April 15th. 1) Must stop in BOS and BKK 2) DONE3 3) maximize mileage 4) my understanding is that there's no oppressive tax at LHR if you're connecting (<24 hours) as opposed to stopping. If I can't avoid the tax, I'll substitute CDG for LHR. 5) starting point is somewhat flexible, looks like TYO hits the balance of convenient to me and cheap price, but I'm open to other suggestions, always. I won't start in Pakistan, it's below my personal safety threshold. CAI would be fine, I've started these there in the past, but my impression is that it's extremely difficult to get one ticketed out of CAI now. Here's what I have so far: NRT-BOS-DFW-ANC-DFW-BOS-LAX-DOH-MAD-DOH-LHR-DOH-ICN-CMB-BKK-CMB-NRT. 55,218 miles according to MileCalc.com.
