The Department of Transportation (DOT) is issuing a $1.2 million fine to US Airways for not providing wheelchair access to airplanes for disabled passengers.
The DOT said the infractions, which took place in 2011 and 2012 at the Philadelphia International Airport and Charlotte Douglas International Airport, were a violation of the Air Carrier Access Act.

The DOT said it discovered the alleged violation of the rules during reviews at the Philadelphia and Charlotte by its Aviation Enforcement Office.
The agency said it found a "significant" number of violations in US Airways's terminals in both airports.
The DOT said its investigation also included reviewing 300 complaints that were filed against U.S. Airways by passengers.
The agency said U.S. Air could use $500,000 of its $1.2 million to pay for disability access improvements.
