Whether to disallow self-modification of airline company names？

[YsMilan]

I submitted a change for the airline company associated with B-12HQ, which was originally uploaded as a private plane. I now know its correct airline company, but it has been about two weeks and the change has not taken effect. Is it now prohibited to make changes on my own? I seem to recall seeing something about this and would like to confirm.

The request is to change from a Private to Dian Yun Airlines

This is a photo of someone else's B-12HQ, with the correct airline:
