Manston cargo is currently running at 36,000 tonnes per annum. That puts it at no 8 in the UK. Given the recent rapid growth, which is not all related to Christmas, and the prospect of DAS Air restarting services, I shall not be surprised to see it at no 6 in the UK by April, as Belfast and Edinburgh are only slightly in front.
This is very heartening, given that the bulk of the infrastructure improvements have yet to come on line. I believe Infratil are saying they are a year ahead of where they expected to be.
