NEWS RELEASE

HONOLULU — September 8, 2008. go! today reported preliminary traffic figures for August 2008 indicating that its operations generated 15.4 million available seat miles, 10.9 million revenue passenger miles and 75,037 passengers, compared with 65,736 in August 2007. Load factor for August 2008 was 70.66%, compared to 71.49% for the same period in 2007. Hawai'i's low fare airline recorded an on-time performance rate of 82%.

In a recent survey completed by more than 4700 go! customers, 89.3% said they thought our iflygo.com website was cool or very cool and 84.2% think our Customer Care and Reservations teams are doing a great job. 77.4% told us they appreciate the ease, simplicity and short walk from the parking lot to our Honolulu terminal, and an overwhelming 89.4% of go! customers rated our friendly flight attendants as great or excellent. Not surprisingly, the highest score of over 90% was reserved for our great low fares, with customers saying they believed fares would skyrocket if go! left the Hawai’i market. That’s why go! is here to stay.

As part of go!’s ongoing support and commitment for communities throughout Hawai’i, go! will donate $1.00 to Muscular Dystrophy Association (MDA) Hawai`i for roundtrips purchased now through September 15, 2008 for travel during the same period. The association helps people with various neuromuscular diseases through research programs, services and education, and go! is proud to give its support for the second successive year.

“The overwhelming support from our customers for go!’s low fares and simplified, friendly service is very encouraging and a real tribute to the spirit, hard work and dedication of our people,” said Mesa Air Group Chairman and CEO. “We are also encouraged by a softening of fuel prices in recent weeks and remain cautiously optimistic this downward trend will continue,” Mr. Ornstein added.
