Do a flight search for an economy ticket, and set it so that you can choose your flight. It goes through Nan and Phrae. As far as whats there, I have no idea. Haven't been there. I was just goofing off and saw it. $25, runs 4 days a week, TG171 and TG172. Actually, it raises the price per segment *slightly*, but this would certainly work as a mileage run. Cost per segment would be around $12.
MAQ-CNX 9am-945am
CNX-NNT-PRH-PHS 1015am-1250pm
PHS-PRH-NNT-CNX 120pm-345pm
CNX-MAQ 420pm-510pm
Each flight is $24 (including tax), so 8 segments into $96 gives $12 a segment.
I think I am graduating into the obsessive category.
I also think I will go to hell for this...
