Depends; are we talking about small engine planes or big jet liners? Some Cirrus aircraft have them, but that's only one particular brand. As for larger aircraft, I'll refer to this link below [0]:
"taking into consideration the added complexity of design, installing and maintaining an emergency parachute system for a typical passenger jet, the amount of revenue lost by carrying at least 40-45 fewer passengers to compensate for installing such a heavy system, and the extremely unlikelihood such a recovery ever would be required, I can't see trying to scale up a parachute recovery capability for airliner use."
