Axios Des Moines: Many are itching to travel this summer, but an influx of vacationgoers is resulting in slightly longer wait times at the Des Moines airport, officials say. More inexperienced flyers are taking to the skies this summer, many of whom don't have TSA PreCheck. Pre-pandemic, 50% of Des Moines airport flyers were business travelers who knew the security screening process or had PreCheck, said airport spokesperson Kayla Korvana. But many companies are waiting to resume business travel until this fall. Only 15% of recent travelers in Des Moines had TSA PreCheck versus the typical 40% of local business travelers, according to Korvana. Airport passengers can expect to wait at least 25 minutes in the TSA screening line and travelers should arrive at least 90 minutes before their departure time, Korvana said.
