US air traffic controllers redraw flight paths to make planes fly straighter

The US aviation authority is updating several air traffic routes in the eastern US. This means planes will fly more direct paths, saving fuel and reducing flight times.

For decades, planes often flew indirect routes because air traffic control relied on ground-based navigation. These updates are part of a larger effort to modernize the entire US airspace system. It means less time in the air for passengers and lower operating costs for airlines.
