Prediction from the Amadeus travel network, refreshed daily.
What disrupts LAS
Vegas runs on point-to-point leisure flying — Southwest above all. Weather is rarely the issue; extreme summer heat occasionally restricts takeoff performance, and weekend crowd surges strain everything from security to gates.
Local knowledge: Sunday evenings are LAS's crunch. If you can fly Monday morning instead, queues and delay risk both drop sharply.
