If CO is ever going to do CLE-ANC seasonal (and CLE-HNL maybe on saturdays would be nice, too), it's probably at least a year away. A few thing have to happen first. 1. The dual runway project needs to start up, which is slated for December of this year or January 2003; 3. CO needs to add feeder traffic in CLE, which won't happen in any significance until the dual runways are up; 3. CO needs the city to lower the landing fees so that CO would fly the route with even a 752.
If that happens, you might someday see a seasonal nonstop CLE-ANC.
