Southwest Airlines is running a deal starting Tuesday offering flights starting at $40 one way from LAX to Vegas, among other deals.
The "SALE-ebrate 2018!" promotion was offering low fares until Jan. 25.
Seats, travel days and markets were limited, obviously, but the prices speak for themselves.
A big caveat – travelers must buy tickets at least 21 days ahead of time. That puts the travel window from Jan. 23 through May 17. Fridays and Sunday are also off-limits.
There are different dates for Puerto Rico and international travel, which can be seen here along with the full list of rules.
