Years ago they announced HEL-BKK-KUL route and even had a large billboard at some. European airports. Before starting the plans changed and HEL-BKK-HKG was alternated with HEL-BKK-SIN.
KUL, Jakarta, Ho Chi Minh City, Manila and once again Hanoi would be great addition but those who know more say that they are low-yielding routes.
