Currently licenses can be for professional flights or licenses for general aviation. If you have a professional license (MPL, CPL or ATPL) you can fly in commercial operations (such as an airline flight). General Aviation Licenses (LAPL, SFCL. BFCL, PPL) are for recreational flights only and no remuneration is obtained with it unless exercising privileges as a flight instructor, for which you must hold the corresponding certificate in force.
