Here’s a rather dramatically deep round-trip discount airfare between the U.S. West Coast and Tokyo: $858 on Korean Air.

To land this deal, purchase your ticket no later than February 3. Then, fly outbound by March 13. You’ll be able to stay over as long as three months on this deal, perfect for flyers visiting family and friends. In any event, you’ll have to stay over a minimum of six days.

At this discount airfare, seats are limited, and so are the days of the week you’ll be able to fly: weekdays only. That means the $858 fare isn’t applicable on Fridays, Saturdays and Sundays. Add another $100 to the tab if you want to fly then.

Taxes and fees are not included in the quote. They’re extra. This is important to remember when budgeting the trip.
