Port Commission of the Port of Seattle and
Board of Directors of the Industrial Development
Corporation of the Port of Seattle
2711 Alaskan Way
Seattle, WA 98121

Ladies and Gentlemen:

In 2001, the Industrial Development Corporation of the Port of Seattle issued its
$64,300,000 Special Facilities Revenue Bonds, 2001 (Northwest Airlines, Inc. Project) (the
"2001 Bonds") on behalf of Northwest Airlines to finance hangar, cargo handling and ground
service equipment maintenance facilities.  Delta continues to operate from these facilities
and has determined that a renancing of the 2001 Bonds would be beneficial and result in
interest savings. Delta has asked the Port and the Development Corporation to assist with
the issuance of refunding bonds by the Development Corporation to renance the 2001
Bonds.

We understand the TEFRA hearing for the refunding bond issue has been held and that the
next step will be the rst reading of the required Port Commission resolution.

On behalf of Delta, I wish to express our full support for the refunding of the 2001 Bonds
and our appreciation of the efforts being undertaken by the Port Commission, the Board of
Directors of the Development Corporation and Port staff to assist us with this transaction.

Sincerely,
iA
Andrew M. Nelson
Managing Director  Assistant Treasurer
