Southwest Airlines has launched its latest twice-a-year blockbuster fare sale, which offers round-trip tickets for below $100 on dozens of routes.
The sale launched Tuesday morning and covers travel from Oct. 31 through Dec. 19, and from Jan. 3 through Feb. 14, CNBC reports. Flights on Fridays and Sundays are excluded, and the sale prices don't cover certain days for Florida and Nevada flights.
Even Southwest's new international routes are included in the sale, though those come with significantly more restrictions.
The sale ends Thursday at 11:59 p.m. in the city of the departing flight.
Southwest has rolled out similar three-day sales each June and October for the past several years -- one sale in June 2015 was so popular that it crashed Southwest's website, according to CNBC.
