For sooner than that we have options available in the next 3 days from $1,553.
Our data shows that October tends to be the cheapest month to fly to Thailand from St. Louis. Users have commonly found prices around $1,711 for the month, but tickets can be as low as $1,241. Due to multiple factors, prepare for potentially higher prices in December.

Got me there and back on time. Except for a 30 min maintenance delay, but that meant more time for nap. Crew was super nice.
