What about switching to CO? They serve LAX and SAN non-stop from NYC and they serve DPS via GUM. I find CO's F product to be miles ahead of DL's and their BF product is superb. Best thing is you can still earn miles if you fly KE NYC-ICN-DPS. EWR-HNL/HKG/NRT-GUM-DPS would probably be a nice routing, but requires two connections instead of one. Other than that AA might be a good choice, but having just switched from DL I am thus far less than impressed, we'll see what happens.
