are you saying you want me to take BKK off the abrv key?
No, no. It would be odd not to have both abbreviations there. Someone who is only trying to find out what an abbreviation stands for, apart from its association with an airport, may notice the Region Abbreviations legend first, and we don't want to confuse or disappoint them. I just appreciate the extra convenience of putting the BKK in the Airport Connections legend. I'm happy with that.
