I would not choose Silkair for very short flights such as KUL or PEN, as taking a flight on LCCs like 3K or TR can be much cheaper even with the emergency row seat selection fee taken into account. However for monopoly routes, I might choose Silkair for a direct link from Singapore. As for Business Class, it is definitely out of the question for Silkair as it does not provide much onboard, except for better food and larger seats. Probably with a PTV thrown in, it's worst considering? What are your opinions?
