PITTSBURGH (KDKA) – If you’re heading somewhere to enjoy the unofficial end of summer, it’s going to be a busy weekend for travel.

The holiday travel season is underway, and travelers who are flying say getting to the Pittsburgh International Airport early is a must.

The Labor Day weekend is always one of the busiest travel periods of the year at the airport.

From Aug. 30 to Sept. 3, there will be more than 108,000 arrivals and departures at the airport. It could make for some crowded flights.

Millions more will be taking to the highways instead of flying.

As far as vehicles on the roads go, the Pennsylvania Turnpike Commission reports summer travel is up this year compared to last.

More than 3.6 million drivers are expected to use the Turnpike this weekend.

There’s good news for drivers, too: the national gas price average is on track to be the cheapest Labor Day weekend average in 3 years at $2.59 per gallon.

According to AAA, this week’s average gas price in Western Pennsylvania is $2.77, just a bit higher than the national average.

To put that in perspective, last year’s average gas price at this time was $3.09.

The GetGo in Carnegie and the BP across the street both have prices at $2.82 — a touch higher than the Western Pennsylvania average.

Friday is supposed to be the most heavily traveled day, with the afternoon being peak travel time.

A heightened State Police force is also expected, so keep that in mind as you hit the road for one last summer trip.
