 United Airlines reports higher profit in the second quarter thanks to record crowds at U.S. airports. United said its profit rose 23% to $1.32 billion in the three-month period that ended June 30th. However, the airline warned that its third quarter results will fall short of Wall Street expectations. That's because airlines are adding more flights than the market can handle, creating a glut of seats that's keeping prices from rising. Correspondent Jeremy House reporting.
