dispatching flights to below minima
 

Hi, as far as I know according to JAR -OPS (now EU-OPS) we can dispatch flights to below minima but we must have 2 above minima destination alternate airport. My question is is there any airline which applies different method for below minima airports. For example choosing a reclear airport on the enroute and check the weather condition of destination over this enroute airport. If the destination is above minimum proceed to destination. If not divert to that enroute alternate. I heard that British Airways use this method. Anyone knows something about that. thnks
