The U.S. military is making its controlled airspace available for commercial airline flights off the East Coast during the July Fourth weekend to help reduce delays for air travelers, allowing air carriers to fly alternate routes in one of the country’s most heavily flown aviation corridors. The Pentagon is releasing the airspace off the eastern seaboard from 6:00 p.m. EDT on Thursday, July 3, to 6:00 a.m. on Monday, July 7. This is similar to what was done over Memorial Day, Christmas and Thanksgiving. The DOD will release airspace off the east coast from Maine to Florida above 24,000 feet, and will continue to control airspace below 23,000 feet for training operations.
