In all honesty, though the ANC airport fees are pretty high, TX and FL have them beat - usually 50-70% more than the quoted base rate just for taxes, fees, etc. that are mandatory. And in those states, going "off-airport" doesn't help much at all.
On the topic of airport fees, it is said that when DL still flew to JNU, that JNU had the highest airport landing fees of any city in the entire Delta network with the exception of Tokyo.
