I've tried to use this code on over a dozen random city pairings in the past 2 days and cannot find a single one where it works. I've tried searching for flights in mid-Sept, early Oct, mid-Oct, and early Nov but can't get a hit. I've tried booking both legs on midweek days and also on Friday-Sunday but can't find any combo that has availability.

The promo rules are specific on date usage for flights to/from Hawaii, Puerto Rico and International but I'm only looking at domestic flights which gets covered in the asterisk of "Use promo code SAVE25NOW from 8/16-8/19 for travel on select flights between 9/4-12/18/2024. Restr., excl., & blkouts apply. Seats/days/mkts lmtd. "

Why bother splashing this promo everywhere if it's actually rather limited and you dont provide any clear, visible way for travelers to use it? https://www.southwest.com/SAVE25NOW/...357905errormsg
