The Port Authority changes the schedules four times per year. The latest changes take place as of March 16th. According to portauthority.org, the 71A and 71B show as: "Weekday service frequency will decrease between 6 p.m. and 7 p.m. and increase between 7 p.m. and 8:40 p.m. to better match rider demand. Trip times will be adjusted for all days." So keep an eye out for new schedules for those routes if you use them. Check www.portauthority.org for more information or for other routes. Bob
