Southwest's big twice-a-year fare sale is back, with round-trip fares below $100 on dozens of the carrier's shortest routes. The sale fares also include longer routes, with the price of flights loosely tied to distance. Flights begin at $49 each way on Southwest's shortest routes and increase to $79, $99 or $129 each way for longer flights.
