How did Elise Eberwein’s role reflect American Airlines’ organizational structure?

"As executive vice president of people and communications at American Airlines, Elise Eberwein’s role within the structure of the organization might not be readily apparent. After all, you might ask, doesn’t corporate communications typically involve marketing? And what does that have to do with organizational structure? As it turns out, quite a bit at the world’s largest airline. When American Airlines and US Airways finally got the U.S. government’s approval to merge in late 2013, it was no longer business as usual for Eberwein and her colleagues at the “new” airline. Until the merger, which basically produced the world’s largest airline with more than 6,000 daily flights and 102,900 employees, Eberwein was head of communications at US Airways—a position she held for nine years after various other jobs in the airline industry. Communications and aviation are in Eberwein’s DNA. She worked as a flight attendant at TWA before moving on to manage communications at Denver-based Frontier Airlines. Her next communications experience was at America West, which then merged with US Airways, where Eberwein served as executive vice president of people, communications, and public affairs before she took over the chief communications job at American Airlines."
