Welcoming our visitors with lei is an important tradition at Daniel K. Inouye International Airport.
Since the 1940s, lei makers have sold their handmade fresh flower garlands at the airport. The lei are made from many kinds of flowers but the most popular are plumeria, orchid, carnation and pikake. Specialty lei are also available. Orchid flowers are popular with those who like fragrance free lei.
Today, 12 Lei Stands are located on the left side of the airport entry road before the Interisland Terminal. The Lei Stands are generally open from 6 a.m. to 10 p.m.
