Check which terminal you fly from before you set off: Southwest, American, Delta, Allegiant and Sun Country use Terminal 1, every foreign airline plus United, JetBlue, Alaska and Frontier use Terminal 3, and the two are not walkable from each other. Arriving, take a taxi from the rank outside baggage claim: the flat fare is $22.25, $26.25 or $30.25 to the Strip depending on the zone, plus a $2.40 airport fee. Leaving, give yourself two hours for a domestic flight and three for an international one, and if your gate is a D gate, allow time for the tram. Through December 2026 the airport connector tunnels have lane closures, so add a few minutes to the ride.
