First, this is definitely a round trip. You can tell by looking at the taxes if nothing else. When the ay is 5.00 - two flights. When the zp is 6.20 - two flights. Plus, the us tax is showing 13.80, which is round trip over the water to anchorage. The one way fare should be half of that. Yes, the one way should be $120.50. That is base of 104.87/3.13us/3.10zp/6.90us/2.50ay totalling 120.50

I work at the change desk so I have those numbers down pat!
