PDX to LAS: Find the Best Deals on Flights from Portland to Las Vegas

First, consider booking your flight at least three to four weeks in advance to secure the lowest fares, as this route is highly competitive between low-cost carriers and legacy airlines. Second, remember that Las Vegas desert heat is intense and dry; even if you are leaving a rainy Portland morning in a heavy jacket, dress in layers to handle the drastic temperature shift upon arrival in Nevada. Third, take advantage of the free Wi-Fi and tax-free shopping at PDX to stock up on travel essentials before you leave, as prices on the Las Vegas Strip can be significantly higher for basic necessities. Finally, try to travel mid-week—specifically on Tuesdays and Wednesdays—to avoid the massive influx of weekend tourists and potentially save hundreds on both your airfare and your hotel stay.

Flight prices from PDX to LAS typically fluctuate based on major events and weather patterns. The cheapest months to fly are usually January and February, following the holiday rush, as well as the peak of summer in July and August when the desert heat is at its most extreme. Conversely, prices spike significantly during March for Spring Break, late December for New Year's Eve, and during massive city-wide conventions like CES in early January or major sporting events at Allegiant Stadium.
