A Message From Bob Muhs
Senior Vice President of Operations

When the Mesaba acquisition was announced, we communicated our intent to
work with our Pilots’ union to find opportunities for furloughed Mesaba
Pilots to move into available positions at Pinnacle.

Today, we’re happy to let you know that we are going to begin preferential
hiring of furloughed Mesaba Pilots into Pinnacle Airlines, with classes
beginning no later than July 26, 2010.

We plan to initially bring back approximately 60 Pilots for the month of
August and continue preferential hiring of Mesaba Pilots through the end
of the year. We also are pleased to let you know that ALPA has agreed on
an MOU that allows those Mesaba Pilots to have their time at Mesaba
applied for the purposes of pay and benefits at Pinnacle. For schedule
bidding purposes, seniority will be based on their start date at Pinnacle,
but Mesaba Pilots will not be required to give up their seniority number
(in order to ensure no seniority integration risks).

Mesaba pilots will receive direct, personal communications soon from John
Spanjers and Joe Restifo.

As we stated during the acquisition and again in the follow-up employee
site visits, we believe this new partnership will create more near-term
and long-term opportunities for our People. Today’s news is just one
example.

Sincerely,

Bob
