MASCOUTAH, Ill. – There is more expansion here at MidAmerica St. Louis Airport as their new general aviation facility is taking shape.

“In the Summer of 2023, we finished the 42-thousand-square-foot expansion of the original terminal,” said Darren James, airport director of MidAmerica St. Louis Airport.  “Now with the addition of this another 25,000 square feet. To your point, the ability to serve more passengers and the community and international destinations is absolutely exciting.”

The facility, being constructed in two phases, will enable the airport to process international and commercial flights.

Just down at the end of the runway is the new Boeing facility, where the MQ-25 Stingray will be built.

“We’ve had more capacity and more passengers in March than we ever had,” James said. “We had 40,000 passengers come through and we expect the same through summertime.

They are working to increase the number of destinations and flights available for travelers in the future, with the right infrastructure in place to help.

“We’ll continue to talk with different airlines,” James said. “Right now, Allegiant is seeking a partnership with Viva Aerobus, a Mexican airline. But other airlines like Sun Country, Velo and Frontier are all going to the areas we look to serve. So we’ll continue having discussions with the airlines.”

Construction on phase 4a began in summer 2024 and is expected to be completed by the end of 2025.
