Frequently asked questions

Is it cheaper to buy a plane ticket from Louis Armstrong New Orleans Intl. Airport (MSY) to Lambert-St. Louis Intl. Airport (STL) last minute?
Being spontaneous is a fantastic way to see the world, but it isn't always the wisest way to score a cheap airfare. Consider booking your Louis Armstrong New Orleans Intl. Airport to Lambert Field trip in advance rather than leaving it until 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 all that spontaneity for when you reach Lambert Field!
