Dont forget that CGN and DUS combined make the largest population area in Germany. There is a strong market for TATL traffic there. yet when I was there last year not many people were aware of CO flying direct to EWR. That is changing my last trip to CGN (this past March) I actually saw advertisement for CO and a lot more of my friends there new about CO. I think given the demand and the few TATL they have from CGN I dont think CO will go anywhere anytime soon...at least I hope.
