Narrative:

During descent; msy approach informed us that 4 drones had been reported at 800 ft. On the localizer and glide slope for runway 11. [Two aircraft from two different air carriers] completed the approach and landed after the first report and reported no sighting before we accepted an approach clearance. We continued to a normal approach and landing and did not observe any drone activity. We have no guidance in our manuals for what action to take when receiving a report of drones. As drones are becoming a more common threat; I recommend that flight ops develops guidance for crews. Specifically; it would help to have a framework for what is a credible threat for aircraft safety and in what cases flight through airspace where such reports has been made should be avoided. It would also be helpful to have reporting procedures and mitigation strategies available.
