There’s a new Southwest sale in honor of the first day of spring that runs through March 29.

It has many more fares and city pares listed than I have seen in the last few sales, though overall fares seem to be about the same or slightly higher as the previous sales.

This sale is good for nonstop flights for spring and fall for the following dates: April 10 through June 13 and August 21 through October 31. There are some black-out dates, including Memorial Day weekend and Labor Day.

It is largely for domestic flights Tuesdays, Wednesdays and Saturdays and international flights Mondays through Thursdays for non-stop flights only (you can often get better deals by taking a connecting flight; see my Southwest deals page for examples).

The extended sale ends March 29, 2018 at 11:59 p.m. in each originating city’s respective time zone.
