Cebu Pacific and state-carrier Philippine Airline are canceling flights to and from Manila due to a scheduled radar shutdown in March. Nearly 4,000 flights are expected to be affected from March 6 to 11 during the maintenance shutdown of the Tagaytay radar. Passengers have been given options to re-book flights, refund tickets, or re-route flights without penalty. The Civil Aviation Authority of the Philippines (CAAP)ordered airlines to reduce flights from 40 to 32 per hour during the said dates at Ninoy Aquino International Airport in Pasay. CAAP Deputy Director General for Operations Captain Manuel Antonio Tamayo says flight radar maintenance should happen every five years, but the Tagaytay radar has not been serviced since 2009. The radar upgrade is a part of an effort by the Department of Transportation to install a “world-class air traffic control system.” The new system is projected to be up and running by June.
