I spent over $2,000 on a recent round-trip flight to Hawaii on Alaska Airlines. I thought I was treating myself to first class, but it was very basic.

The sale ends tomorrow, Jan. 9, at 11:59 p.m. PT and is available for travel dates between Jan. 28 and March 19. Hundreds of routes are on sale, according to the airline, with the lowest one-way fares bookable for $39 or 4,000 miles and minimal taxes and fees.

Those looking to explore the nation’s final untamed frontier may want to take advantage of non-stop flights from Sacramento to Anchorage, Alaska this summer. Starting June 14, Alaska Airlines will be offering seasonal non-stop flights from SMF to Anchorage.
