If watching Lost is as close as you get to taking that Pacific Island dream getaway, then Air Tahiti Nui's Spring in Tahiti sale might be just the thing.
Now until June 26, you can fly from LAX nonstop to Papeete, Tahiti for $758 round-trip, and from JFK for $858 round-trip. These fares are good for travel from LAX on April 24, May 8, May 17, May 31, June 9, and June 20. From JFK, this deal is good any flight between April 27 through May 22.
We were able to find JFK to Papeete for $940 round-trip, including taxes, and $777 round-trip, including taxes, from LAX. But seats are limited and this deal expires May 4, so you may want to hurry.
