Southwest has launched a flash sale for travel in April/May in which it says that its offering one-way fares from $69, but fares on some routes are lower than that. It is also running a seperate flash sale offering 30% off base fares to/from Hawaii which is valid for travel in August and September.

Both sales only run through 21 March (tomorrow) and as usual, there are a lot of terms and conditions to navigate (e.g. you can only travel on select days of the week if you want to book the best fares), but a quick look at some of the deals on offer shows that there’s still value to be had on some routes..

General example fares (April/May sale)

These are just some example fares that I found by doing random searches.

Sadly, these fares are not as low as the lowest fares that we’ve seen on these routes in recent years (we’ve seen some of these as low as $29 in the past), but the fares we’re seeing this time around seem to be a little lower than they were the last time one of these flash-promotions was offered.

  • From $50 one-way nonstop between Los Angeles and Sacramento
  • From $50 one-way nonstop between Nashville and Chicago (MDW)
  • From $50 one-way nonstop between Denver and Salt Lake City
  • From $64 one-way nonstop between Boston and Chicago (MDW)
  • From $70 one-way nonstop between Chicago (MDW) and Houston (IAH)

On some dates, the fares on these routes are considerably higher than on others so using the flexible calendar search will be the best way to find the good deals.

Quick thoughts on the Hawaii sale

The best fares that I managed to find started at ~$165 one-way and on many routes, I struggled to find any discount at all.

At the beginning of the year, we saw Southwest offer fares starting from $109 for one-way travel between the West Coast and the Hawaiian Islands, so this doesn’t look like a particularly great sale to me.

Still, if you’re set on traveling to/from Hawaii in August or September, it’s worth checking out these fares to see if they’re better than what the competition is offering, but if you’re expecting to book an amazing deal you’re probably going to be disappointed.

Bottom Line

Southwest is currently running two separate flash sales and both are set to end tomorrow. As usual, these sales come a ridiculous number of terms and conditions, so make sure you take a look through all of the restrictions before you start making plans.

The best way to find the lowest fares is to use Southwest’s Low Fare Calendar which, in the case of the Hawaii sale, appears to automatically include the promo code and which should quickly show you if your preferred routes have any great deals on offer. Flexibility with your travel dates will be key to locking in a good saving.
