Probably a repost but i didn't see any thread discussing this.
Pretty cheap non-stop first class with lie back one ways to/from NYC/HNL around new years on Delta. Presumably these are the empty legs. Probably won't get a good RT itenerary out of this but one way for $538 in first is pretty reasonable.
An example:
$814
12/28/2017 9:30 AM – 4:14 PM
New York City (JFK) – Honolulu (HNL)
Delta 2019 · First Class · Boeing 767
Lie flat seat
or
$538
5:37 PM – 8:25 AM+1
Honolulu (HNL) – New York City (JFK)
Delta 1330 · First Class · Boeing 767
Lie flat seat
Overnight flight
