Frequently asked questions

Is it cheaper to buy a plane ticket from Lambert-St. Louis Intl. Airport (STL) to KLU last minute?
Being the spontaneous type is a rewarding way to travel the world, but it isn't necessarily the best method to pick up a cheap fare. It's better to book your STL to KLU journey well ahead of time 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. We recommend saving that spontaneity for when you arrive at your destination!
