Aviation Technical Services Expands Airbus Service Offerings

Everett, WA (June 4, 2014) - Aviation Technical Services (ATS) has expanded its Airbus service offerings
with an Airbus 330 modification program for longtime customer Hawaiian Airlines as part of the airline’s
previously-announced Extra Comfort premium economy seating. The interior passenger reconfiguration,
which began in 2013, has been installed by ATS on five of the airline’s 12 aircraft to-date and is
scheduled to be complete this summer.

The installation transitions the cabin interior to a lighter color scheme, and adds five additional inches of
legroom in Rows 11-14 and 33-34 of its Extra Comfort seating.

“This project is a logical continuation to the 10-year partnership with Hawaiian Airlines and our growth
in support of Airbus operators,” said Matt Yerbic, ATS President and CEO. “We have been able to rapidly
work together to deliver updates to seats, interior and IFE.”

“We are excited to give our guests more options with the addition of our Extra Comfort seats to
enhance their in-flight experience with the product offerings they value most,” said Executive Vice
President and Chief Commercial Officer Peter Ingram. “The new class of seats that are being installed by
ATS on our Airbus A330 aircraft are available for purchase now when booking online, for travel on or
after Aug. 1.”
