Scottie’s Take

This is the kind of Southwest sale we’ve been waiting for. If you’ve got points saved up, now’s the time to use them. I’m seeing roundtrips from Honolulu to the West Coast in the 19k–22k point range, which is a solid redemption. Remember, Southwest points are tied to cash prices, so when a big sale like this drops, your points go further.

For local travelers, this is also a smart time to book family trips for early 2026 before prices climb again. Just make sure you double check blackout dates around Thanksgiving, Christmas, and New Year’s.
