    Delta is making it easy for customers to donate online to help offset
carbon dioxide (CO2) emissions associated with their air travel. Customers
who wish to make a donation can select "Plant Trees to Offset Carbon
Emissions" under "Trip Activities" when booking a flight at delta.com. At
nwa.com, customers can make a financial contribution directly to The Nature
Conservancy(R) or make a donation to help offset carbon emissions
associated with their flight when they book.

    "We have a responsibility to preserve and protect our planet's natural
resources," said Tim McGraw, Delta's director of Corporate Safety, Health
and Environmental Programs. "Delta remains committed to helping our
customers and employees worldwide take action while also serving as a
global corporate leader through a variety of ongoing environmental
programs, including our carbon offset programs."

    All donations made at delta.com go to The Conservation Fund's Go
Zero(R) program to plant trees and restore habitat for wildlife across the
United States. All donations made at nwa.com are directed to The Nature
Conservancy's Voluntary Carbon Offset Program to acquire and protect land
in priority conservation areas, plant trees and restore forest on those
lands, and monitor and verify the carbon benefits.

    Delta was the first U.S. airline to provide a carbon offset program in
partnership with The Conservation Fund in 2007. Through that program,
nearly 100,000 trees have been planted and 262 acres restored at three
national wildlife reserves, including Lower Rio Grande Valley along the
Texas Gulf Coast, Marais des Cygnes National Wildlife Refuge in Kansas and
Red River National Wildlife Refuge in Louisiana. The newly planted forests
help absorb carbon dioxide, filter water, restore wildlife habitat and
enhance public recreation areas.

    Delta's carbon offset program is one of the airline's many efforts to
effect positive, global environmental change including:



    --  The improvement of fuel efficiency by 35 percent since 2000.
    --  The reduction of annual water consumption by more than 150,000,000
        gallons per year since 2004 through process improvement and elimination
        of unnecessary water usage.
    --  The diversion of more than 1.8 million pounds (923 tons) of aluminum,
        plastic and paper products from community landfills since June 2007
        through the airline's onboard recycling program.

    --  The promotion of modernized Air Traffic Control (ATC) systems worldwide
        that afford more direct aircraft routing, resulting in the reduction of
        carbon emissions.
    The Conservation Fund and The Nature Conservancy are part of Delta's
Force for Global Good, a program that unites Delta employees and customers
in philanthropic and social responsibility efforts.
