During business hours and early AM or early evening--Security Lines can be huge!!! Long! 30-45 min. Arrive early unless you are First Class .

If you want a bottle of soda the vending machine has them for $2.25 final price. At the concessions they're between $2.45 and $2.69 BEFORE TAX.

TSA try hard but the set up for lines is all wrong. Make time if during peak hours. Ancient airport with cheap upgrades. Everything from the rental shuttle to baggage claim and "signage" is a joke

Made it thru security with no problem! TSA was great! Be patient and give yourself time

Wear slip-on shoes and when you're done, please move to the benches to put them on and repack. The lines are slow enough.

Welcome to STL!

It takes 45 minutes you get thru security on a good day.

Worst & most illogical TSA process. Why do your frequent flyers have to go thru the full body scan & the occasional travels go thru the old fast ones?

Security was great. ... Fast. Easy trip:)

A Concourse security is a hot mess 90% of the time

Security was a giant cluster, a bunch of unhappy women arguing over who's turn it is to do what while the line didn't move.

TSA pre check took less than five min!

Now tornado free!

Security line wasn't long, but was horribly SLOW. Leave some extra time and prepare for a thorough pat down.
