Forgive me for not understanding but surly the CAA stats for both legs include those routing SIN-IAH and MAN-IAH and vice versa.
Can you tell from IAH figures published that the 3000 marked as IAH-SIN dosnt include MAN traffic?
The route makes no sense for SQ if they are bad as this unless there is some business contract at play.
Not looked at the websites where the figures are located but way I read is, its more less 50/50 IAH to SIN and MAN if you look at the 3,000 figure and the 6,000 for MAN-IAH figure.
