Please do not send any more airport updates to Robin; the gateway will go into beta soon, and we’d like to use it to collect all future changes. (You can only imagine how much work it was for Robin to gather up 750 airports by hand! We imported them into the gateway ourselves to test the gateway and get control of the process.)
