While CO does not have anywhere near the route structure of DL, they do have some interesting niches. For example:

- UK regional airports (MAN, BHX, Glasgow in addition to London)
- Central and South America
- Hong Kong
- Micronesia
- almost as big in Europe in DL.

Their main weakness is their domestic route system - particularly in the SE and West.

BTW, I know I'll get berated for saying this, but I'm not sure the service at CO is really that much greater than DL.
