After looking at multiple logo redesigns, I found the new logo of Delta Air Lines had a positive transformation. One might claim that not much has been altered from the prior trademark, but I argue otherwise. Occasionally in design, small changes can make big differences.  When comparing both versions, I could tell the font has changed from a Serif type to a San Serif type, I could also tell the color has changed from a blue into a deeper blue, and last but not least, the figure changed from one dimension into a two dimensional perspective. All these to minor changes has completely given the logo a new and different feel. Now it looks modern and fresh.
