Frequently asked questions

Is it cheaper to buy a plane ticket from PDX to MMH last minute?
When it's time to book your flights, it's better to be prepared. While you may be able to find a last-minute deal on a PDX to Mammoth Lakes Airport flight, prices usually don't get cheaper as the date of departure nears. Based on flight pricing and demand studies in 2022, we have found that the sweet spot to book a domestic flight is between 28 – 35 days ahead. For international travel it's three to four months.
What airports do you fly into for Mammoth Lakes from Portland?
There are two — Mammoth Yosemite Airport (MMH) and Bishop, CA (BIH-Eastern Sierra Regional). Both are good options for those traveling from Portland to Mammoth Lakes.
