Frequently asked questions

Is it cheaper to buy a plane ticket from PWK to STL last minute?
When it's time to book your flights, being prepared pays off. While you could pick up a last-minute deal on a Chicago Executive Airport to STL flight, prices usually don't get cheaper as the departure date nears. Based on flight pricing and demand studies in 2022, we have found that the sweet spot to book a domestic flight is between 28 – 35 days in advance. For international trips it's between three and four months.
