I agree with you to a point and logically Emirates would expand at GLA when the time comes but this may leave a door open at EDI to a competitor and such competition may remove the level of price control that Emirates currently enjoys at GLA. Ironically should they choose to close the back door they may end up with competition in their face at GLA which may be a worse situation but we are all just guessing.
You are correct about the ethnic population in Glasgow but the figures are still very small at just 3% (2001 census) and no asian country figured in the top 20 final destinations from GLA on the 2005 CAA survey.
Logic says expand at GLA but looking at recent route decisions in Scotland airlines seem to have had logic bypass surgery.
