I set an alias in my shell so this is just 'airport', lets you interact with the wifi settings - I particularly like 'airport -s' for doing a scan of the local wifi networks, since it shows signal strength and channel information right there, which is helpful when troubleshooting.

It also separates 2.4GHz and 5.0GHz bands and shows security details (which matters sometimes e.g band steering or automatic same-SSID signal-strength-based AP selection doesn't work)
