150000 miles each for LAX-HNL in First? If so, then DFW to HNL is actually cheaper, 120000 miles each and $21.40 in taxes.
DFW to OGG is another awesome route in First class but availability is a bear.
ETA - nevermind, I see that LAX-HNL in First is only 75000 miles each so DFW-HNL or DFW-OGG would be much more expensive, at 120000 miles each. Sorry!
