The US web site isn't showing the non-stop CLT_HNL on the 19th or HNL-CLT on the 26th (Tuesdays - what's up with that?), so departing on 1/20/2010 and returning on 1/27/2010 (7 day stay, round trip):
US $858 + taxes fees (CLT-HNL-CLT)
DL $774 + taxes/fees (CLT-ATL-HNL-ATL-CLT)

ps - don't know if it's a web site issue, but the CLT-HNL-CLT flights don't show operating on Tuesday starting on 1/19/2010 and resuming on 2/16/2010. If that's right, the trip over on Monday the 18th through Monday the 8th of Feb will be nice trips - 2 nights and all day in HNL.
