Question

What is the Flag Carrier airliner of the United States?

Answer 1

There is not a single flag carrier airline in the United States.  The airline industry has been deregulated, so there is no single state-run or state-sponsored airline.

There are many airlines involved in "flag operations", meaning any airline that is approved by the FAA to operate a scheduled service between:

-Alaska or Hawaii and any point outside of Alaska or Hawaii,

-Between any of the 48 contiguous states and a point outside the 48 contiguous states, or

-Between any two points outside of the United States.

Among the major carriers, American, United, Delta, Northwest, US Airways, JetBlue, and Continental are all involved in flag operations.

Answer 2

American Airlines.

of course, there's no government investment in any airlines, so that title is "unofficial"
