Honolulu to Stockholm, Sweden $684 round-trip, incl. all taxes
Nevermind why you'd trade a single day of mild Hawaiian winter for a few freezing days in Stockholm's dark winter (just kidding, we love a good glögg!), this is a pretty terrific fare! Here's the thing, there is a slight trick to finding this price. Our Orbitz links will take you to their fare calendar where the lowest fare shown is $933 round-trip. See that? Good. Select the $933 fare that best suits your travel dates and you'll notice the fare magically drops to $684 on the following page. Neat, isn't it?
We did notice a few dates in late March where our little trick didn't work so well, but you should have no problem searching in January, February, and early March.
