The S7 flights banner ads promote peace between Russia and the Ukraine, amidst the massive amounts of turmoil that's happened over the past few months.
The banners show the words Moscow on one side, and Kiev on the other with a peace sign in the middle. Although it's quite a simple message, the S7 flights airline has done a great job in taking a hot political topic, and turning it into a branding opportunity. Moreover, the company is actively promoting peaceful actions between Russia and the Ukraine.
Considering the precarious situation between the two countries as of late, any small amount of support for a peaceful resolution of the conflict is welcome. Although this obviously serves the S7 airlines own branding initiatives, at least it promotes social good at the same time.
