Washington DC - From the crowded terminals in Chicago's O'Hare to the confusing layouts of Washington's Dulles and Los Angeles' LAX, many US airports aren't exactly in top shape.

To expand capacities, improve energy efficiency, and make terminals more passenger friendly, the government is now planning to invest almost $1 billion into the country's airports.

According to the White House, a total of 85 airports across the country, including California's Los Angeles International (LAX) airport and Denver International Airport, are set to receive a financial boost.

The hub set to make the most gains from the funding is Boston, with the city's international airport set to get $62 million.

The project, part of a $1-trillion infrastructure bill, is intended to improve conditions for passengers, provide more efficient freight transport, and make the US more competitive in tourism and other sectors.

"America is a country that brought the modern aviation age to the world," Transport Secretary Pete Buttigieg said.

However, in worldwide rankings, US airports rarely made it into the top 25 when it comes to quality, he added. "That's something that we have to change."

As the US is recovering from the Covid pandemic, passenger numbers are on the rise again, Buttigieg said.

The US was economically dependent on air travel to move both goods and people around the country and the world. Meanwhile, it was visible elsewhere how airports and airlines struggled to keep up with demand, the Transport Secretary said.
