Taiwan-based airline STARLUX on Thursday said it aims to operate up to five daily round trips between the island and Hong Kong in the future.

Its first flights between Hong Kong and Taipei will take off on July 16, with two round trips each day.

Tony Cho, the airline's mainland China chief representative and Hong Kong branch general manager, said the coming year is the right time to boost passenger flight frequency, when Chek Lap Kok's third runway comes into full operation.

The airline is capable of increasing its manpower from the current 18 members of staff stationed in Hong Kong, Cho added.

"We have to compete with each other among this industry, but we also cooperate with them," he said. "We need more frequency to serve Taiwan and Hong Kong, and other areas for our business."

In celebration of the new flights, a STARLUX-themed tram will run until the end of September, and there will be a sightseeing journey across Hong Kong Island later in July.

Hong Kong Tramways, which has partnered with the airline, said the collaboration will attract more tourists from Taiwan to visit Hong Kong.

Nixon Cheung, the tram operator's head of commercial and brand, said the public transport firm has seen a surge in passengers.

"We do have a great rebound during the past years, especially when we have many free ride days, that catered to a lot of customers, especially tourists flying from all over the world," he said.
