Since 09 September, 2020 when the Turkish-Azerbaijani alliance had not yet unleashed a war against Artsakh and Armenia, the flights of Armenian-registered planes through the airspace of Turkey have been banned without justification.

The actual application of the unannounced ban became known after Turkey rejected the requests of Armenian aircraft operators to fly over its skies. Check out the full report on Hetq.
