A likely reason for why only Qatar airways reports this is that they are notorious about regularly publicly complaining about “quality issues” in the press during commercial negotiations. It’s a trick to pressure the aircraft manufacturer. That’s not to say that quality issues don’t happen, they certainly do. But QTR is known to be very quick to refuse to work with their supplier and publish the complaint in the press, instead of working it out like is the norm, especially if it’s near a time of contract negotiation.
