Tips for 45 min Connections
Gates are all within a two-to-three minute walk of each other, so tight layovers are more about flight punctuality than terminal size.
TUS has minimal connecting traffic, so gate agents and staff can often help rebook quickly if you're worried about a tight connection.
There is no dedicated international arrivals hall, so if traveling from abroad you'll clear any required processing before reaching the concourse.
The single small checkpoint moves fast most of the day, but arrive with buffer during early morning and early evening banks when local business travelers cluster.
Bring snacks or plan ahead — concession options are limited compared to larger connecting hubs, so don't count on a quick meal between flights.

Getting Between Concourses
TUS has one terminal with all gates accessible by a short walk down a single concourse, so there is no shuttle or train system. There is no international arrivals facility, so all connections are handled as standard domestic transfers through the single shared security checkpoint.
