There is already legislation in the UK for this. Your company operations manual should have the statement
If the journey time from home to normal departure airfield is usually in excess of 1 1/2 hours, crew members should make arrangements for temporary accommodation nearer to base.
If the normal travelling time is in excess of 1 1/2 hours then the crew member concerned is in breach of the company ops manual in the same way as if a duty was rostered in excess of Max FDP. Of course using the word
Should rather than
must does cloud the waters somewhat.
