From March 15th, 2017 to August 27th, 2019, 100% user give 5-star rating. for Airport Code Explainer chrome extension.
Airliners.net changed a few years ago to where this was no longer an automatic feature. Glad to have found this extension.
This both helps me know where I am about to land as well as alert me to when I've mistyped an airport code in a tweet. Five stars because it won't let me put ten.
