America West is still paying the leases on all their gates in Concourse B. Their lease doesn't expire until December of this year, so even though they're not using all the gates, they still owe money to the airport. United has been using some of the Dew bridges on the north side of the terminal, and Independence Air is supposed to be using gates 16 and 18, which are America West's. I'm not sure how that agreement was made (HP leasing the gates to DH, etc). But there's no way HP will ever ramp up service in CMH again. The city of Columbus is totally against the airline now, Southwest is slowly eating away at their loads, and the airline has dropped the evening Las Vegas flight. I wouldn't be surprised to see them out of Columbus entirely in the near future.
