"This is tactical because the situation in Hong Kong has not been conducive and demand has declined," he said.

The airlines will return to normal frequency if conditions in Hong Kong improve.
Planes that normally fly to Hong Kong were now diverted to other routes with high demand, Ikhsan said.
"We use the aircraft to add frequencies on other routes that have good requests," he said.
Not only Garuda, but nearly all airlines have reduced the frequency of flights to Hong Kong at this juncture, he added.
The current situation in Hong Kong is heating up following the numerous student demonstrations and the clashes with the police which began with strong protests against the extradition law last August.
The protests have reached the Hong Kong International Airport, where a number of flights were disrupted.
