DCA-OGG in F is the same price as SEA-OGG 
Well, its close but not exactly the same. The longer haul(most east coast and AK) first class fares to Hawaii connecting in SEA are usually ~ $700 ($676 or $701 before taxes) while the SEA-OGG or HNL first fares are about $550. Still a deal for a x-country first flight for only an additional $150.
For example:
11/14
DCA-OGG -- $701+
SEA-OGG -- $551+
Some other cities like MCO are more, usually ~$800++.
