Hi @CptnDoppie
I see you’ve found the FSElite article with the list of airports included in the first batch of World Hub updates. We posted the list yesterday in the News & Announcements category: World Hub Airports & Navdata Update (Cycle: 2402) - Official Microsoft Flight Simulator / News & Announcements - Microsoft Flight Simulator Forums
We currently do not have a list of the specific changes for each airport, although these are available for viewing for those who have signed up to the World Hub Alpha test. When the World Hub goes live these will be viewable for everybody.
Users are able to edit elements like jetway and parking placements, runway elements, windsocks etc. but not able to place down objects such as new hangars or terminal buildings. We’ll look to provide a full list of elements that can and can’t be edited within the World Hub soon.
Thanks,
The MSFS Team
