AD PLACEMENT — CONTEXTUAL
If your connection spans Terminal 3 and Terminal 4, use the Sky Train rather than trying to walk or catch a bus, as it's faster and more frequent.
American Airlines connections are almost entirely within Terminal 4, so same-terminal transfers can be quick even with a short layover.
International arrivals clear Customs in Terminal 4's S-gates area, so budget extra time even for a short connecting flight afterward.
PreCheck lines at both terminals are typically fast and can save significant time during Southwest and American peak banks.
Check your gate assignment as soon as you land, since Terminal 4's concourses (A, B, S1-S3) can require a longer walk than expected.

Low risk
Moderate
High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
The PHX Sky Train, an automated people mover, now directly links Terminal 3 and Terminal 4 (extended in 2022), replacing the old inter-terminal bus for most travelers. Within Terminal 4, moving between the A/B concourses and the S1/S2/S3 international gates requires a walk or a short shuttle, and international arrivals go through a dedicated Customs and Border Protection facility before re-entering the domestic side.
