Frequently asked questions

Is it cheaper to buy a plane ticket from Lambert-St. Louis Intl. Airport (STL) to IGR last minute?
Being a spontaneous soul is a wonderful way to travel the globe, but it isn't necessarily the smartest way to land a bargain airfare. It's better to book your Lambert-St. Louis Intl. Airport (STL) to Mayor Carlos Eduardo Krause Airport 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 reach Mayor Carlos Eduardo Krause Airport!
