HONOLULU- go!, the interisland Hawaii division of Mesa Air Group, Inc. (NASDAQ: MESA), today celebrated its 239,000th passenger with a fabulous go! Vacations gift package.

After flying on go! from Hilo to Honolulu, Joyce Murata of Hilo was awarded a go! Vacations package, which includes roundtrip travel for two on go! and two nights accommodation at a deluxe hotel of her choice on Oahu, Kauai, Maui or the Big Island. On arrival in Honolulu, Murata was greeted by members of go!'s team: Joe Bock, Chief Marketing Officer; CD Lauritsen, Chief Operating Officer; and Bette Brumlow, Regional Stations Manager.

This is great, I was telling Bette on the flight over that the biggest thing I ever won was a Big Mac from McDonald's," said Murata. "This is kind of like all a shock to me and I don't think it's really sunk in yet," she added.

Murata was traveling to Honolulu to visit her husband who commutes to Honolulu from Hilo weekly for his job. Murata says she has already booked his flights on go! for the rest of this year. "I have to say the go! staff and the Hilo crew have been amazing. If there are any problems we can't fix on our own we just give them a call and they're very accommodating," said Murata.

"We're delighted that nearly a quarter of a million customers have experienced go!'s great fares and service since our launch in June and we think that's worth celebrating" said Bock. "With the lowest fares and the best vacation packages in Hawaii, we look forward to sharing the go! experience with a further 239,000 happy customers in the months ahead," he continued.

go! thanked every passenger on board the lucky winner's Hilo to Honolulu flight with a gift of go! luggage tags.

go! selected the milestone number in honor of its trademark $39* fare. "Reaching this milestone of our 239,000th passenger after just a few short months shows beyond a doubt that the people of Hawaii have truly embraced our really low fares," said Jonathan Ornstein, Mesa Air Group Chairman and CEO. "go!'s low fares have stimulated the market with more people than ever flying and spending the money they saved on other goods and services in the local community and that's great for everyone in Hawaii," he continued.
