kkfernweh, welcome to FlyerTalk!
I noted that you've cross-posted this to the Information Desk forum here:
http://www.flyertalk.com/forum/infor...awaii-nyc.html
As FlyerTalk disallows cross-posting and that is the better forum for the thread, as you do not have United miles, but could construct the trip using carriers which honor your other rewards/airline miles or points, I'll close this thread and invite discussion to continue in the Information Desk thread.
