Company Policy
Air Carrier ABCD and Company Air Carrier ABED were both on approach to Runway XXL and Runway YYR; both on frequency at the same time. A cautionary advisory was given to the trailing aircraft. [Same Company's flights] EFGH and EFIH were consecutive arrivals; no cautionary advisories were given to the pilots. Fortunately there were no hear back/read back errors in either of these instances. But since both aircraft were on approach and on Tower frequency at the same time; it would have been easy for one aircraft to take a landing clearance or runways crossing instruction intended for the other. This Company has known for a long time about similar-sounding call signs here and their potential impact on operations.
Tower Controller voiced concern regarding the continued use of similar sounding call signs by one company even after the company was notified of the potential safety factor.
