We all know how volatile air fares are so this could completely change in five minutes but just for discussion's sake I checked travelocity for First Class fares LAX-HNL-LAX.
I pulled the dates of Jan 13th out and back the 20th out of thin air.
Hawaiin DC-10 or 767
United 757 or 767
American 757-200 or 767-300
I have seen ads in the Los Angeles Times Sunday travel section for First Class bucket fares and for sale frequent flier tickets for $1,250.
Last year Delta was quoting $1,200 DFW-HNL-DFW First Class on their now defunct L-1011 non-stop flights.
