Airlines on this route
Alaska Airlines, Spirit Airlines and Southwest Airlines fly this route nonstop. That matters more than it sounds: the cheapest fare on one carrier is rarely the same product as the cheapest on another.

Leaving from Portland (PDX)
Plan to be at the airport two hours before a domestic departure — ninety minutes can work at smaller airports outside peak times, but security lines are the one variable you can't control. If you're checking a bag, add time rather than cutting it close. Our Portland airport guide covers terminals, parking and ground transport so you can plan the trip to the airport, not just the flight.
Arriving in Las Vegas (LAS)
Before you land, know how you're getting from the airport to where you're staying — it's the part of the trip people forget to plan. The Las Vegas airport guide lays out your ground options, from transit and shuttles to rideshares and rental cars. Flying back the other way? Check Las Vegas to Portland fares — prices on the return direction often move on a different rhythm.
When to book
For a trip of 763 miles, booking 2–4 weeks ahead typically lands you in the sweet spot. Leave it to the final two weeks and prices usually climb as the cheapest seats sell out. If your dates are flexible, midweek departures are where the lower fares hide on most domestic routes.
Good to know before you go
- Screenshot your fare before you enquire — prices move, and a saved fare helps our team match or beat it.
- Flexible dates? Search a few days either side — one day can change the fare a lot.
- Morning flights are delayed less often than evening ones — earlier departures have the best on-time record.
- Basic economy fares often exclude checked bags and seat selection. Price the whole trip, not the headline fare.
- Get to the airport two hours before departure; security, not the flight, is the part that runs late.
