Singapore Airlines is reducing Asian services in its winter schedule while adding flights to Saudi Arabia. Reductions include services between Singapore and Osaka, Seoul, Penang and Ho Chi Minh City. “Where demand falls, capacity reductions will be made quickly,” the airline says. The airline hasn’t specified the percentage change in capacity. Several of the changes will be gradual. One daily flight on the Seoul service will be wound down until it is suspended completely from Feb. 2 to March 28.

Designers on the Superjet 100 by yearend are likely to decide which stretched model of regional jet to pursue, says Superjet International CEO Alessandro Franzoni. Designers are still busy trading seat-count and range to devise the right solution. Options appear to have narrowed to a 120-seat model, which would be brought to market quickly, in about two years, or a 130-seat model. However, the latter would require more extensive work, including bigger changes to the engine and wing (a composite wing is being considered), Franzoni says.
