Hi I am looking for advice please. We are flying from Sydney Australia to Hawaii on 13/8/13 . We are scheduled to arrive at Honolulu airport at 7.45am and would like to fly to Maui that morning. Can anyone please advise me how long I should leave between flights. We have never been to Hawaii before and not sure how long it will take to get through customs etc and then get to the domestic flight terminal. Should I book now or is it practical to book a flight when we get there so that I do not have to worry about delays etc. Thank you in advance.
