MANILA -- Cebu Pacific, Jollibee and Oishi have pledged to promote Philippine destinations, the Department of Tourism said Wednesday, as a new cash-based budget is expected to "slightly" trim funds next year.

The country's largest airline, Cebu Pacific, offered to help the tourism department campaign against littering, Tourism Sec. Bernadette Romulo-Puyat told ANC's Headstart.

Jollibee and snack food maker Oishi both pledged to shoot and air commercials to promote Philippine destinations for free, she said.

"Our budget is a little smaller but we're good with it because what’s good with us a lot of people in the private sector have been willing to help us…There’s a lot of goodwill, a lot of people who just want to help the country," she said.

The department will also keep the "It's More Fun in the Philippines" slogan started by President Rodrigo Duterte's predecessor, former President Benigno Aquino III.

"I want continuity. Other countries, they’ve had their slogans for decades. Tayo, palit nang palit pag may bagong administrasyon, bagong secretary," she said.

(We keep changing our slogan when there's a new administration or a new secretary.)

"With me, it works. It’s more fun in the Philippines, and I want to continue it. Why change something that works? It’s a good campaign," she added.

Romulo-Puyat, a former agriculture undersecretary, said she would promote destinations "that people don’t normally go to," such as the island provinces of Siquijor and Camiguin.

She also wants to boost awareness on sustainable tourism and the heritage festivals in the country.
