You don't say whether you were observing during the day or at night, but as a matter of preference, if not policy, some pilots prefer landing lights off at night to improve the visual acquisition of the runway environment. The backscatter of light through the fog/cloud will reduce the contrast with approach lighting, and other visual landing aids. the fact that all AA arrivals used the technique certainly suggests that policy might play a role, but airlines also develop cultural quirks that go beyond policy. Use of lights is usually an ops policy matter.. -- David A. Domino MITRE Corporation firstname.lastname@example.org (703)883-3695 My opinions, not MITRE's.
