Deal Alert: Southwest fares as low as $29 or 1,100 points each way

Southwest is no stranger to flight sales, and $29 fares are hard to ignore — especially when paired with the airline's phenomenal Companion Pass, which you can still snag with little effort for the next few days.

This week, the airline is offering discounts on flights booked by 11:59pm CT on Thursday, March 4, 2021. Travel dates range from April 13 through June 2 for eligible domestic and international flights, and through May 26 for flights to and from Hawaii.

You likely won't see the lowest advertised fares every day — weekend flights are generally excluded, and certain mid-week days may not be available, depending on the route.

Here are some examples of flights you might find discounted as part of the sale:

• As low as $29 one-way between New Orleans (MSY) and Houston (HOU)
• As low as $29 one-way between Baltimore/Washington (BWI) and LaGuardia (LGA)
• As low as $29 one-way between Phoenix (PHX) and Palm Springs (PSP)
• As low as $54 one-way between Nashville (BNA) and Fort Lauderdale (FLL)
• As low as $99 one-way between Long Beach (LGB) and Honolulu (HNL)
• As low as $99 one-way between Long Beach and Maui (OGG)

As a general rule of thumb, the shorter the distance, the lower the fare — you won't find transcon flights or hops to Hawaii within that $29 range. There are plenty of low-cost flights available, though, such as Salt Lake City (SLC) to Las Vegas (LAS) for 29 bucks:

Or just 1,058 points, plus the $5.60 TSA fee:

You can score that bargain-basement price on flights between the Hawaiian islands, too.

Fares between hubs can be quite reasonable as well, such as the $49 you'll pay each way between Dallas and Chicago.

Or you can lock in your flight with an entire reasonable 2,510 Rapid Rewards points, plus the $5.60 security fee.

Flights between the mainland and Hawaii are on sale as well, though they'll cost you a bit more.
