Is it cheaper to buy a plane ticket from Trivandrum Intl. Airport (TRV) to Lambert-St. Louis Intl. Airport (STL) last minute?
Being spontaneous is a wonderful way to explore the world, but it isn't necessarily the smartest method to grab a cheap airfare. It's better to book your TRV to Lambert-St. Louis Intl. Airport (STL) trip well ahead of time instead of 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. Leave your spontaneous side for when you get to your destination!
