Frequently asked questions

Is it cheaper to buy a plane ticket from Lambert Field to SAT last minute?
Being a spontaneous soul is a wonderful way to explore the world, but it isn't always the ideal way to track down a cheap airfare. It's better to book your Lambert Field to SAT trip well ahead of time rather than waiting 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 SAT!
