Uh, the 737's are going to replace the -400's and the MD's.
Also you cannot make $$ with a 737 to HNL. That is a big reason Aloha is sending back 3 of thier aircraft and had to pull out of YVR. You can only take 80% load after your ETOPS fuel from the Pac NW to HNL in a 737. With today's profit margins, that will not do!
