- Discount is valid on new reservations only.

Quick Thoughts
These Southwest promo codes aren’t valid on all flights and itineraries. If there are any discounted flights for your routes/dates, you’ll see a green banner at the top stating ‘Score! Promo code BUZZER has been applied.’ Eligible flights will then have an original price struck through, with the discounted price displayed in green below.
For any awards where there’s discounted airfare pricing, if you switch over to points pricing you’ll see those same flights discounted too.
If you have any existing Southwest flights booked during the promo period, it’s worth repricing them to see if they’re eligible for the BUZZER promo code discount.
