From Jacksonville, I recommend flying from Jax—> Atlanta—> Honolulu with Delta (best route and ride. They actually feed you and you get in by 2 pm HST). I would recommend giving yourself at least an hour layover in Atlanta when booking because it can take 30 + minutes just to get to your connecting gate and there is usually only 1 flight to Honolulu. Better price point with United from Orlando (MCO) —> LA or Houston —> Honolulu I strongly recommend AVOIDING two + layovers because the normal flying time is a lot already and extra stops make it a very long day with the time change from the east coast!
