Choose your departure date, but stay flexible to save. Even though your return ticket is open, for most airlines you'll need to know when you want to arrive in Maui before you can book your outbound ticket. Being flexible with your departure date may save you money.
Find out which airlines fly to Maui. This can be done by visiting a travel agent or by calling the airlines directly. The primary airport for Maui is Kahului, though many flights arrive into Kahului via Honolulu International Airport. Maui also has two other airports - Hana and Kapalua. A number of airlines offer flights to one of these airports, including Hawaiian Airlines, U.S. Airways, Delta, and United.
Contact each airline and ask them whether they offer open-ended tickets to Maui. Some may not. Make a list of the airlines that do offer open-ended tickets, and compare the prices and available departure dates of each.
Find the best option for your trip and book your ticket. Upon booking your ticket, you will have to confirm your departure date, but your return date will be left open. You can book your ticket by phone, directly with the airline or you can use a travel agent.
Enjoy your flight and your trip, but be prepared to let the airline know your return date as soon as possible. You are not guaranteed a seat on a return flight until you have confirmed it with the airline; so, once you know your desired return date, contact the airline or your travel agent to book your seat.
