"We have received an absolutely tremendous response to the HERO fare. Friday we experienced our biggest day of sales and stimulated an amazing amount of activity in our frequent flyer program and other web-based products," said Joe Bock, Chief Marketing Officer for go!. "Our mission statement is to bring the friends, families and business people of Hawaii together and that is exactly what we're doing. We couldn't have asked for a better outcome," he continued.

go! operates 64 flights every day from its Honolulu hub to Lihue, Kahului, Kona and Hilo using a fleet of new generation regional jets.

"We want to apologize to our competitors who are clearly very upset with our low fares," said Ornstein. "Fortunately for our passengers, go! is a highly efficient airline bringing much needed competition to the skies of Hawaii. Possibly the most successful airline in the world gives away over twenty percent of its seats for free and is highly profitable because of its low costs and complementary income sources. We are emulating this model with go! and will continue to be Hawaii's low fare leader," Ornstein added.
