A while back I started a thread in the same vein. The rules were:
1. Travel had to be non stop and originate/terminate in the same state.
2. The fare had to be the lowest published fare.
3. The flight had to be regularly scheduled.
4. The question was: Which is the most expensive.
There was some fun discussion and ANC (Anchorage) to ADK (Adak) was the winner at around $1200.
