Airlines for America
Nick Calio became president of the Air Transport Association (as Airlines for America was then known), in January 2011. Calio was hired after the Republicans made big gains in the 2010 midterm elections. Hiring Calio, "a brand-name Republican," known for working well with Democrats, was seen as a positive for the ATA. Democratic lobbyist Jimmy Ryan said: "He’s so well liked by both Democrats and Republicans that for the ATA it’s a huge coup. The new challenge is figuring out how to get things done in a bipartisan manner and Nick is the guy who’s got the record to do it.” U.S. Senator Harry Reid said, "...Nick was a straight shooter and I appreciated that about him when he was at the White House. The ATA is fortunate to have a seasoned hand who understands the importance of finding bipartisan solutions.”
Calio was Citigroup's head of government relations. During Calio's seven years at Citigroup he expanded the firms government relations staff from two Washington-based lobbyists to 18 people working in 12 countries. Calio also managed Citi's legislative strategy during the debate over financial reforms that eventually produced Dodd-Frank. Calio mentioned that the financial crisis showed the value of personal relationships. He said, "Over the course of your career, treat people well, make sure they trust you and you’ll have a better platform to work on issues even in a very sour environment." 
In 1971, Calio graduated from Charles F. Brush High School in Lyndhurst, Ohio. Calio received his undergraduate degree from Ohio Wesleyan University, graduating in 1975, and graduated from Case Western Reserve University School of Law in 1978.
