The logo was created for America's bicentennial celebrations.
In early 2000, Delta were persuaded by Landor Associates to make a number of changes to their identity. This included dropping "Air Lines" from their logo and softening the arch in the triangle.
2004–2007[]
In July 2004, Delta reverted back to the sharper widget symbol, partly due to employee suggestions and to coincide with the company's 75th anniversary on June 17, 2004. There were, however, no other changes to the livery.
On April 30, 2007, Delta Air Lines presented a completely new look, the same day the airline emerged from bankruptcy. The triangle is now all red, with one side in a slightly darker shade to give the symbol some depth.
