I’m aware of NOTAMS (notice to airmen) which are issued for launches of rockets, as for example mentioned in this [answer](https://space.stackexchange.com/a/2936). The same seems to be the case for deorbiting second stages (see [here](https://space.stackexchange.com/a/7821) and [here](https://space.stackexchange.com/a/13174)).

On September 8, a video taken by the pilots of flight LX178 from Zurich to Singapore was released by Swiss Radio and Television ([twitter](https://twitter.com/Wgcdr_Enriquez/status/906266919833137158)). It appears that the pilots were surprised (first thinking of a meteor) and thus were not aware of the re-entry of Soyuz MS-04 on September 3. 

Are scheduled re-entries such as for Soyuz announced in advance and does it have consequences on commercial aviation?
