The flight route from New York (NYC) to Hawaii (ITO) is one of the longest within the U.S., but most certainly worth the trip. A non-stop direct flight is offered by Hawaiian Airlines und United, promising to fly you the distance of 4900 miles in a flight time of just over 11 hours. Although travel among the islands is relatively efficient one should still choose the most convenient airport for one's total trip. The options are Hilo International Airport (ITO), Kona International Airport at Keahole (KOA), Upolu Airport (UPP) and Waimea-Kohala Airport (MUE).
To secure a low cost air ticket be sure to book long before the departure date, being careful to avoid holidays, school vacation periods and weekends. Be willing to fly with only your hand luggage and be sure to compare prices online before buying.
Once you've landed you have pretty instant access to the treasures of the islands since local transport is good. Shuttles are the cheapest ways to get to and from the airports and renting a car is the best way to experience the real Hawaii. On Oahu there is a well established bus system to take advantage of. And if you plan to hop between different islands consider flying with Aloha Island Air - they even have a special six flight coupon book.
