Hawaiian Airlines will match Aloha Airlines' promotional one way fare of US$249 between Honolulu and Pago Pago.
Aloha's special fare sale, which went into effect the middle of last week, is based on a round-trip purchase.
The fare applies for bookings made between now and May 26th for travel between May 12 and October 7th.
Hawaiian spokesman Keoni Wagner says the decision to match Aloha was in order to remain competitive in this market.
Hawaiian will match the fare starting from tomorrow.
Both Aloha and Hawaiian each operate two weekly flights.
