Airlines for America (A4A) has projected that 16.1 million passengers will fly worldwide on US airlines over the upcoming Labour Day travel period, marking a 5% increase from the 15.4 million passengers that travelled during the same period last year.

The annual seven-day holiday period, which falls between 30 August and 5 September, is expected to see the Hartsfield–Jackson Atlanta International Airport (ATL), Los Angeles International Airport (LAX), and O'Hare International Airport (ORD) as three of the busiest airports in the US.

According to A4A, among the seven days, 1 September will be busiest at the three airports since the number of departing passengers is estimated to be the highest on that day.

"Flyers can rest assured that US airlines have appropriately increased the number of seats available for their late summer getaways.”

In order to fulfil the projected demand, US airlines are adding 133,000 seats a day across their networks.

A4A vice-president and chief economist John Heimlich said: “As household wealth increases, ticket prices remain low and airlines large and small continue to grow, consumers are finding it easier and more affordable than ever to get away for personal or family travel.

“While we expect a growth in passenger traffic over the Labour Day holiday, flyers can rest assured that US airlines have appropriately increased the number of seats available for their late summer getaways.”

A4A further noted that US airlines are making regular investments in their workforce and new technologies, as well as adopting processes to improve operations and customer experience.

The US Department of Transportation’s Bureau of Transportation Statistics data reveals that the US airlines carried 823 million passengers last year, which includes 719 million domestic travellers.

The volume exceeded the 2015 record, reported Reuters.
