Goodness! Sure seems like the Delta management would worry about more important things than that. They already have too many liveries flying around, seems like it hurts the "brand" to have a bunch of different designs around all at the same time.
They're really working hard to reinvigorate this airline!! They're changing FA uniforms, they're making it so that you can't talk to an agent face to face (only on the phone, ala Delta Direct), and now they're changing their livery.
Good grief!!
