It has recently been announced that Delta will be painting a Boeing 767-400ER pink for the Breast Cancer Research Foundation. This aircraft will be replacing a Boeing 757-200 currently in a different pink livery, which will be repainted into standard Delta livery. The reason for the switch is because Delta wants to spread the word on breast cancer internationally; the 757-200 that currently wears a pink livery only flies domestic routes. The aircraft should be repainted on May 25.
Here is a rendering of the aircraft:
Reminds me of smooth jazz!
