We debated a layover, but wound up making the right decision for our family. Yes, going out was long, 11 hours nonstop from Newark, but discussing it later with my husband and 2 older sons, we all felt that once we were "on the plane" we would not have wanted to layover for an hour or so in the airport, only to have to board again. I guess we all feel that we wanted to "gut it out and just do the nonstop". Return trip non stop to Newark is 9 1/2 hrs. There is one United Non stop per day I believe. We flew out of Newark at 9:15EST, arrived Hawaii time 2:15. The return was a red eye...left Hawaii at 8:10, arrived Newark the next day at 12:00PM. I "watched" the fares and researched fares for about 2 months prior to the 7th month booking window. We traveled the day after Memorial Day and I got a great fare, but unfortunately when I researched it seemed that after the 2nd week of June, the rates shot up for the entire summer, except for the last week of August I believe. I believe that we paid $742 round trip, but fares in June, July, August were $1,000 at least.. Up until the 7 months, our dates were running at $715 round trip, then went up to $742... Best of Luck Booking. PS...Met a couple from NY at Aulani and they raved about Hawaiian Air from JFK! Hope that you love Aulani! We DID! Hoping to get back in 4-5 years!
