The post 7 innovations that Southwest is testing to improve its crucial turn times is a great real-world example of experimentation in product (make sure your ad blockers are charged for this one, it’s published on The Points Guy…).

Zach Griff goes over several ideas Southwest Airlines are trying to improve the time between when a flight arrives and leaves again. For instance, for when you’re queuing on the jet bridge:

The first is the installation of Bluetooth speakers in the jet bridge, which play (royalty-free) disco, electronic dance music, hip-hop and kids music during boarding and deplaning. Listening to music at a high beats-per-minute rate is scientifically proven to get people moving faster and more efficiently, according to McCartan, which is exactly what Southwest wants during one of the most critical phases of the turn.

There are lots of learnings for PMs sprinkled throughout the post.
