Frequently asked questions

Is it cheaper to buy a plane ticket from St. Louis Downtown Airport to HNL last minute?
Being spontaneous is a terrific way to explore the world, but it isn't always the best way to land a bargain fare. Think about booking your St. Louis Downtown Airport (CPS) to Honolulu Intl. Airport trip well in advance rather than leaving it till the 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. Save up that spontaneity for when you get to Honolulu Intl. Airport!
