This is my recent experience as of 3 weeks ago..
Was looking to do an aerobatics course. First things first emailed Airborne, Curtis, and Air Combat.
Curtis received email same day
Air Combat received next day
Airborne.................................................... ...........Still Waiting
Went for a visit
Curtis - within 2 mins greeted with friendly people and introduced to instructor to answer all my questions
Airborne - walked in, must of been wearing my ghost costume. I could see them but ahaaa they couldnt see me. Finally got a rushed non specific info (takes about 7 hours and here are the rates goodbye)
Air Combat closed. Was in the late afternoon
Kind of easy to guess which one i chose
