Trying to book a Southwest flight with a discount code is like trying to win a prize on an obviously rigged claw machine game.

Depends on where you're going. Blackout dates for Continental U.S. travel are 5/21, 5/22, and 5/25.
My trip isn't on blackout dates and it still says there are no available flights... yet when I select from the low fare calendar, they are listed but the promo code is removed from my cart. Even with the discount though, it's close to the same price United is advertising through Kayak.

Southwest was my favorite airline to fly, good value in the bags and boarding was easy peasy. Now they charge for bags and charge for upgraded seats that are hardly an upgrade, if you don't pay then you are stuck three wide even if they rest of the airplane is empty.

Flown them 4x since the change, and they were more expensive than other airlines but I wanted my miles and such but now I am actively booking other airlines for work if they are even $1 cheaper.

Was watching a fare over the weekend and with the promo code on the same fare it was actually more. Do your homework y'all. Hope someone can find some deals.

I'm seeing cheaper flights through other airlines like United and Delta for my dates. I don't think this is an actual sale.

They have ancient planes but at least the selling point was 2 free checked in bags and you get to pick your own seat if you checked in exactly 24 hours in advance. Now they have no unique selling point but still ancient planes.

Don't see any reason why the coupon code wouldn't work but it says it can't be validated. Looking to use the remaining SW points I have and hopefully never fly them again but I guess I can't do that yet!
