Travelers boarding morning flights from Pittsburgh International Airport are being told to arrive two-and-a-half to three hours ahead of time.

A message posted on the airport’s Facebook page offers advice to people on flights that take off between 5 a.m. and 8 a.m. to account for longer ticket and security lines.

Officials report record-breaking crowds this summer, resulting in longer than usual TSA security lines. Airport authorities say they are working with the TSA to streamline the security process.

It won’t be until next year when a new terminal opens with 11 TSA lanes, including a dedicated family lane.

PIT officials say several airlines are expected to offer a record number of seats at the airport this summer.

In July, at least five carriers are expected to break a record for their monthly capacity offerings at PIT, which includes “bidirectional seats” – a combination of arriving and departing flights and the number of seats offered within them.

Southwest Airlines will operate nearly 298,000 bidirectional seats in July, the most it has ever offered in a month at Pittsburgh since starting service in 2005. It is also the most seats offered by any airline at PIT in one month.

American Airlines will offer nearly 262,000 seats for the month, the highest the airline has offered in Pittsburgh since its merger with US Airways.

Spirit Airlines will offer more than 144,000 bidirectional seats during the month, its highest since entering the Pittsburgh market in 2017.

Frontier Airlines will fly nearly 49,000 bidirectional seats at PIT, its most since returning to the area in 2016.

Breeze Airways is scheduled to operate nearly 29,000 seats, its largest amount of monthly capacity since beginning service at PIT in 2021.

“They’re adding new routes and bringing bigger aircraft on current routes,” said Joe Rotterdam, director of Air Service Development at PIT. “And for many of our carriers, they’re scheduled to fly more passengers this summer than they have since 2019.”
