In early 2000, Delta were persuaded by Landor Associates to make a number of changes to their identity. This included dropping the words "Air" and "Lines" from their logo and softening the arch in the triangle.

2004–2007

In July 2004, Delta decided to revert back to the sharper widget symbol, partly because of employee suggestions. There were however no other changes to the livery.[1]

2007–present

On April 30, 2007, Delta Air Lines presented a completely new look, the same day the airline emerged from bankruptcy.[2] The triangle is now all red, with one side in a slightly darker shade to give the symbol some depth. Lippincott Mercer created the new identity.
