MANILA - The Department of Transportation on Thursday touted fewer flight delays and the end of the bullet-planting extortion racket in airports as among its achievements in President Rodrigo Duterte's first 100 days in office.

Removing general aviation from the Ninoy Aquino Aquino International Airport helped increase on-time arrivals to 71 percent from 47 percent, said undersecretary for aviation Bobby Lim.

Aside from having no incidents of the "tanim-bala" scam, toilets in the terminal once dubbed by a travel website as among the worst in the world have also been renovated, Lim said.

Headway, or the waiting time between trains at the Metro Rail Transit, was reduced to 4.5 minutes from 5 minutes, said undersecretary for rail Noel Kintanar. The number of breakdowns was also reduced, he said.

Easing daily traffic jams in the capital, however, was difficult in the first 100 days, Transportation Secretary Arthur Tugade said.

President Rodrigo Duterte is seeking emergency powers from Congress to help solve the traffic problem that results in an estimated P2.4 billion in daily economic losses.
