You'll have to excuse American Airlines CEO Doug Parker if he finds himself looking around as he adjusts to life as the man in charge of the world's largest airline.
He has finally climbed the mountain.
For the first time in his career, Parker no longer has to focus on making his company bigger by aggressively lobbying and maneuvering for, and ultimately pursuing, a merger.
"There's still a lot of work to do to bring these airlines together, but today is a big step," Parker said before ringing the Nasdaq opening bell via remote from American headquarters in Fort Worth, Texas.

But now that his former carrier, US Airways, has teamed up with the formerly bankrupt American Airlines to form the new American, Parker faces the real test: making money.
And let's be clear. Investors do not expect the new American to be simply profitable, but very profitable. Especially given that it is coming out of bankruptcy with a cleaned-up balance sheet, faces only moderate jet fuel prices and has an improving economy.
"We have to provide a return to our investors. We know that," Parker said. "The last 10, 11 years have proven that airlines that can't do that aren't allowed to grow and expand and do the things we want to do. We expect to produce a profit."
New American, new advantages
The merger of US Airways, formerly the fifth-largest airline, and the old American, formerly the third-largest, creates the world's largest airline as measured by available seat miles—calculated by the number of seats on a plane and how many miles the plane will travel on a certain trip.
More important, the company is now a global giant with a strong domestic and international route network.
