On days of 100% flight operations-which is Monday, Thursday, Friday and, for the most part, Sunday, the outbound banks are:
-8AM, eastbound flights
-930am, westbound and southbound flights
-1130am-eastbound and southeast bound flights
-1pm-westbound and southbound flights
-330pm-eastbound and southeast bound flights
-5pm-westbound and southbound flights
-7pm-eastbound flights and southeastbound flights
-830pm-westbound and southbound flights
Within each bank, you'll find an occasional flight going in the opposition direction, like a EWR
during a westbound bank, and an IAH
during an eastbound bank.
And most airlines probably don't follow a schedule at CLE
near CAL-they'll follow a schedule that flows into their respective hubs.
As for COEX to CO
ratio, I'd say it's more like 70/30 in favor of COEX.
