More than 100 Monday flights had been affected as of 4 p.m. The FAA said later in the afternoon that operations were normalizing after repairs were made.

SAN ANTONIO — Faulty air condition inside the air traffic control tower at San Antonio International Airport resulted in dozens of delayed flights Monday as officials warned travelers to stay updated on their travel status. 

Officials with the Federal Aviation Administration said it was slowing flights out of the facility, citing air conditioning problems in the air traffic control tower. 

At 5:35 p.m., the FAA said in an update that operations were returning to normal after “technicians have fixed the tower’s air conditioning system.” 

The airport initially posted on X about “higher-than-normal air traffic delays” at 2:48 p.m. As of 4 p.m., the airport had experienced 102 flight delays, according to FlightAware data; nearly half were flights where San Antonio was the “origin” airport facility. Incoming flights from Atlanta, Dallas, Baltimore/Washington, Houston and elsewhere were also delayed. 

For context: There had been an average of 77 daily delays over the weekend, according to FlightAware. The airport has not experienced any outright flight cancellations so far. 

It was 92 degrees at the airport at 3:51 p.m., according to the National Weather Service, with the heat index – or “feels-like” temperature – at 97 degrees.
