Labor Day Flights Will Be Some Of The Busiest EVER, Experts Predict

Buckle up -- it's gonna be a looong ride.

Labor Day air travel in the United States will be even busier this year than last, following a summer that will likely break all-time records for air passenger numbers.

U.S. airlines are expected to carry 14.2 million passengers worldwide from Wednesday, Sept. 2, through Tuesday, Sept. 8, up 3 percent from a year earlier, Washington-based trade group Airlines for America said on Tuesday.

In other words, airfare is unbelievably cheap right now, and everyone knows it. Get ready for a jam-packed Labor Day flight and crowded airports to go with it.

Airlines for America has forecast that summer travel will reach an all-time high on the wings of a strong U.S. economy. Passenger traffic grew 3 percent in the first half of 2015, although a 3-percent decline in fares during the same period kept operating revenues flat for U.S. carriers, Airlines for America said.

Yet a 34-percent decline in fuel costs, airlines' greatest variable expense, has boosted their profit.

"Six years post-recession, airlines are finally realizing profit margins that are on par with the S&P 500 average, a barometer of U.S. corporate performance," the group's Chief Economist John Heimlich said.

The 10 publicly traded U.S. airlines collectively had a profit margin of 11.2 percent in the first half of 2015, up from 4.9 percent in the prior year, according to the group.
