Arriving in Manado from Singapore by SilkAir is always a good experience. The greenery around the airport was beautiful and the short walk (less than 2 minutes) from the plane to the immigration counter is a relief compared to the 10-15 minute walk I used to have in Changi when rushing from immigration to the gate. The terminal building is quite clean and adequate. The only downside is the crowd outside the arriving gate exit. There were lots of illegal taxis touting arriving passengers. The lack of seating area outside the terminal is also a concern as it was hard to find a proper place to sit while waiting for someone to arrive.
