BUS fares on Lantau Island will increase by 10.5 per cent on Saturday. The new fares include an extra 10 cents to $1.30 per trip on weekdays and between 10 cents and $2 per trip on weekends and public holidays. The New Lantau Bus Company plans to make further savings by replacing five double-deckers with air-conditioned coaches. It said double-deckers were less efficient than coaches, both when operated with fewer passengers on weekdays and when used for a large load on winding and hilly terrain at weekends.
