NINETY-DAY NOTICE OF TERMINATION OF SERVICE

Pursuant to Part 323 of the Department of Transportation’s Regulations (14

process of retiring all turboprop and numerous small jet aircraft operated by Mesaba and

Pinnacle. All of the Saab 340 aircraft operated by Mesaba for Delta Connection will be

retired by year end. Delta has notified Mesaba and Pinnacle that high fuel costs and low

passenger demand further necessitate the filing of this notice.

Mesaba and Pinnacle are commonly owned by Pinnacle Airlines Corp. The

markets may need to be back-filled by Pinnacle-operated regional jets until a

replacement carrier is selected. With the Department’s permission, Pinnacle is currently

providing substitute service in select Mesaba EAS markets. This notice is intended to

cover all Pinnacle/Mesaba service at Greenville, regardless of which carrier may be

providing service during the transition period. In the event the Department requires a

hold-in, the carriers request that Mesaba and/or Pinnacle be authorized to provide the

service, and that the Department set reasonable and fully compensatory rates based on

the use of CRJ aircraft, which are the only aircraft available to provide continued service.

The discontinuation of service will c ause service to drop below the EAS

guarantee levels established by the Department. Mesaba and/or Pinnacle is the only

carrier providing service. Complete schedules including routes, arrival and departure

times, equipment types, and operating carrier(s) are as follows:
