iniBuilds have recently shared a single screenshot showcasing the upcoming free passenger variant expansion for the A300-600R(F) aircraft for X-Plane 11. The freight variant is scheduled to be released in August 2020. The release date for the passenger variant is unknown.
Based on the Facebook post, the passenger variant is on the horizon. On the screenshot, we can see Thai Airways A300 (HS-TAW) approaching Daxing. The screenshot might not represent the final product as it is still a WIP image.
