This is due to repulsive nature of charge....
When we give charge inside any conductor , Charges get repel each other and moves through the conductor till each one distributed uniformly so that net force on each equal to Zero...
When we charge inside the conductor , charges comes out the surface , but do not fly off in air as the dilectric constant of air much higher...So charge Remain at the surface of conductor...
If you conncet the long conductor to the charged conductor , then Charges easily flow to the connected conductor and lastly comes out to the surface due to repulsive nature....but not in air...
If any how charges have greater dilectric strength than air , then charges can easily flow in air also...This happens only of charges have much high energy in order to breakdown the dilecteic strength of dilecteic...This is we observe during lightening, When charges have greater dilecteic strength than air...so charges flow in air which gives the effect of lightening....
