       SUMMARY OF ASSIGNMENT AGREEMENT, DATED AS OF JULY 1, 2003, BETWEEN
              DELTA AIR LINES, INC. AND CERTAIN EXECUTIVE OFFICERS

In 2002, we restructured our officer life insurance program by replacing the
existing group policy with individual policies under a split dollar program that
were owned by the covered executives. This change enabled us to reduce the total
cost of the officer life insurance program. As with the previous program, we
paid all premiums for the insurance policies, which were treated as interest
free loans to the executives. Each executive then assigned a portion of the
value of his or her policy to Delta to cover repayment of the loans made to pay
premiums. Delta filed the documents pertaining to this matter, including a form
Loan Agreement and Collateral Assignment Agreement, with the SEC in its Form
10-Q for the quarter ended September 30, 2002.

Because the Sarbanes-Oxley Act, which was enacted following the initial
restructuring of the program, prohibits such loans to executive officers, it is
necessary for us to restructure this program to eliminate the loans for payment
of policy premiums and to provide for repayment of the existing loans. To effect
this restructuring, each executive officer transferred his or her policy to us
by means of the Assignment Agreement, a form of which is this Exhibit 10.4. This
transfer from the executive to us of the cash value of the policy repaid the
loan that paid the initial premium on the policy. We now own the policies and
all cash value in the policies belongs to us, rather than to the officer, and
consistent with the intent of the program, the officer retains the right to name
the beneficiary of the policy.
