Cape Air cancelled all Sunday flight due to the weather.
Despite less-than-anticipated snowfall, airport director Jarred Hester said delays at Lambert-St. Louis International Airport caused problems.
"These uncontrollable type of delays would have lead to missed connecting flights and added significant burdens to our travelers," he said. "By cancelling flights in advance and notifying the passengers, people can determine the best course of action for their travel arrangements."
Flights are expected to resume Monday morning.
