Frequently asked questions

Is it cheaper to buy a plane ticket from University Of Illinois Urbana-Champaign Williard Airport (CMI) to Incheon Intl. Airport (ICN) last minute?

Based on flight pricing and demand studies in 2022, we have found that the best time to book domestic flights is between 28 – 35 days ahead of the departure date, and international flights three to four months in advance. Leave your spontaneity for when you're discovering ICN!
