does it really take an a/p license to park a plane..or push it back for that matter..mechanics all went to school to learn a trade..according to you 30% dont use it...before us/pi merger there was no recieve and dispatch.. a part time ramp agent could park and launch an aircraft with pi..or a ramp lead with us..and as far as utility goes..except for us maintenance bases,,there was none...ramp also did that along with flt crews and catering..
