I submitted a flightplan at 0200z for a 1300z departure by skydemon for which I quickly received a acknowledgement. By submitting at this unusual time I hoped I might catch them when they weren't too busy! By 1200z I'd heard nothing from Atlas so I phoned, managed to get through easily only to be told a text message had been sent sometime previously. No text has been received so far and its almost now STD. Anyone else had this experience? People on phone at Atlas most helpful and gave me my number.
