Indeed, Delta announced a multi-year agreement Wednesday that they've struck with TB12 -- making him a new long-term strategic adviser for their company ... which will see him give their employees, their customers and their stakeholders a piece of his mind on a number of topics -- including general greatness, something that's right up his alley.

Here's how the CEO pitches this ... "Delta’s people are driven by their commitment to world-class performance, excellence and a desire to achieve best-in-class results. Bringing a leader like Tom onto the Delta team furthers our mission to connect the world while accelerating our drive to continuously improve for our colleagues, customers and communities."

Specifically, Delta says Brady will assist them in developing/advising on strategic training and "teamwork tools" for their more than 90,000 workers. He's also going to be the new face of Delta, it seems, when it comes to marketing for current and prospective ticket buyers.

And finally ... Delta says TB's going to get involved in their shared "communities," but are kinda vague on what exactly that means. In any case, they've landed a major whale here.

As for Tom himself, he's quoted as saying ... "I am grateful to be joining the Delta family, a company I have loved and respected for years," Brady said. "Growing up with a mother as a flight attendant, I have always admired the people that make seamless air transportation possible. Throughout my career, my teammates and I flew Delta countless times, spending hours traveling for some of the most important games of our lives, even celebrating Super Bowl wins on the plane."

He adds, "Those championship teams were built off of great leadership and a commitment to excellence, and Delta certainly shares those qualities. Now, alongside Ed and the Delta team, I look forward to playing my part to continue the company’s success."

No word on what the money looks like here, but ya gotta imagine Brady's making a fortune off of this ... as he seems committed for the long haul, and his services don't come cheap these days. Remember -- he signed a 10-year, $375 million contract with FOX Sports already. Plus, he's got tons of other sponsorships under his belt -- Hertz and so many more.
