Tips for 1¾ hr Connections
Southwest, American, United, and Delta gates are spread across the single concourse, so check your gate change board immediately after deplaning.
If arriving internationally, budget extra time for Federal Inspection Services, which can back up during multiple wide-body arrivals.
AUS security lines can spike sharply during weekday morning and Thursday-Sunday evening banks tied to SXSW and event travel, so don't assume off-peak calm year-round.
The South Terminal used by Frontier requires a separate shuttle and is not connected airside — never book a tight connection through it.
Because AUS is not a true hub for any carrier, missed-connection rebooking options can be limited to a handful of daily flights, so ask agents about interline options early.

High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
Getting Between Concourses
All main connections occur via a single level walk through the central terminal corridor connecting the East and West concourses; there is no train or shuttle required. Passengers arriving internationally must clear Federal Inspection Services in the FIS facility before re-entering the sterile area, which adds a walk and a processing queue not needed for domestic-to-domestic transfers. The South Terminal, used by Frontier and a few low-cost carriers, is a separate landside building reached by a short shuttle bus ride and is not practical for tight connections.
