I tried Atlantic Aviation at Addison for the first time and will not go back. After the first night, the line guys showed me exactly how they had accidentally damaged the paint on my nose wheel fairing with a tow bar they normally use on jets. However, Atlantic management would take no responsibility for the damage. The second night, I called ahead to tell them I needed to depart at 9:00 the next morning. When I arrived, my Cessna was block in by a Gulfstream that they would not move until the Gulfstream's owner showed up two hours late.
