AD PLACEMENT — CONTEXTUAL
If your connection spans Terminal 1 and Terminal 3, budget extra time for the tram ride plus walking distances within each concourse.
International arrivals into Terminal 3 require a full Customs and Border Protection process, so build in at least 90 minutes if connecting onward.
Southwest passengers connecting within Terminal 1 (Concourses B and C) generally have the shortest walk of any pairing at LAS.
Check your gate as soon as you land since Spirit, Southwest, and international carriers can be assigned gates far apart within the same concourse.
Use the tram rather than walking between terminals since the outdoor/indoor walking path is considerably longer and less predictable.

Moderate
High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
An automated tram links Terminal 1's Concourses A, B, and C with Terminal 3's Concourse D, with the full ride plus walking taking up to 20-25 minutes end to end during busy periods. International arrivals at Terminal 3 must clear US Customs and Border Protection before rechecking bags and proceeding to a connecting flight, which adds significant time regardless of which terminal the next flight departs from.
