Singapore Airline is going to make major changes on its air routes in a bid to streamline its air operations. The carrier may increase frequency to various routes besides suspending operations to some destinations including Pakistan and Nanjing in China. The last Singapore-Karachi-Lahore flight and Singapore-Nanjing service would be on February 17 and March 26.

In a declaration, the airline said, "Positive signs of a recovery in demand continue to be seen but operating conditions remain challenging and yields in particular remain under pressure. SIA will continue to carefully match capacity to demand across the network."

The frequency on the Singapore-Moscow-Houston route would be increased five times per week from December 18 onwards. Singapore to Newark daily non-stop flight would be operating daily against earlier schedule of five times a week.

Frequency on Singapore to Seoul route would also be increased 18 times on weekly basis from June. However, the number of flights to Ho Chi Minh City and Kuala Lumpur would be decreased.
