Flying from Nashville to St. Louis: what you need to know
The flight
Nashville to St. Louis is a short hop — 272 miles, about 1h 3m gate to gate on a nonstop. You'll spend almost as long taxiing and boarding as you will in the air, so the real time-saver on this route is picking flight times that dodge rush hour at both ends.
Airlines on this route
Southwest Airlines flies this route nonstop. That matters more than it sounds: the cheapest fare on one carrier is rarely the same product as the cheapest on another. Checked-bag fees, free seat selection and change rules all differ, so compare the full trip cost before you pick a winner. See our airline guides for exactly what each carrier charges — then send an enquiry and we'll confirm the all-in price for your dates.
Leaving from Nashville (BNA)
Plan to be at the airport two hours before a domestic departure — ninety minutes can work at smaller airports outside peak times, but security lines are the one variable you can't control. If you're checking a bag, add time rather than cutting it close. Our Nashville airport guide covers terminals, parking and ground transport so you can plan the trip to the airport, not just the flight.
Arriving in St. Louis (STL)
Before you land, know how you're getting from the airport to where you're staying — it's the part of the trip people forget to plan. The St. Louis airport guide lays out your ground options, from transit and shuttles to rideshares and rental cars. Flying back the other way? Check St. Louis to Nashville fares — prices on the return direction often move on a different rhythm.
When to book
For a trip of 272 miles, booking 2–4 weeks ahead typically lands you in the sweet spot. Leave it to the final two weeks and prices usually climb as the cheapest seats sell out. If your dates are flexible, midweek departures are where the lower fares hide on most domestic routes.
Good to know before you go
- Screenshot your fare before you enquire — prices move, and a saved fare helps our team match or beat it.
- Flexible dates? Search a few days either side — one day can change the fare a lot.
- Morning flights are delayed less often than evening ones — earlier departures have the best on-time record.
- Basic economy fares often exclude checked bags and seat selection. Price the whole trip, not the headline fare.
- Get to the airport two hours before departure; security, not the flight, is the part that runs late.
