Not sure about the 737 drivers but all QF 767, 744, A330 and A380 pilots are low viz qualified and current if the skipper has autolanded within the past 35 days. We have low viz approaches as part of our recurrent sim 'training'.
All the aircraft are maintained to the required standard- most days- and autolands carried out by aircraft on approved runways using low viz procedures at least once every rolling 35 days.
