From the screenshots, regardless of being converted or new, the terminal buildings looked already quite advanced 3 months ago, even showing the interior, suggesting it was close to release. It was also supposed not to be a long waiting time anymore 1 month ago. Just saying the communication can be improved here like posting the progress made or reason for any delay, especially when people are interested and ask for updates.
Taking ages in my view compared to the other airports (Cologne to be released 1 month after preview for ex). Announced mid August showing a well advanced product from the screenshots and still not there almost 3 months later.
