When you first gain your Commercial Pilot’s Licence, you will typically look for work in the field of joy flights, parachute drops, day VFR charter such as traffic reports, and possibly flight instructing (with the addition of a flight instructor’s rating).
The next step is typically a Multi-Engine Command Instrument Rating (ME/CIR) which can lead to charter work or regular freight runs.
After you have gained more experience, you may be in a position to apply for regional airlines or national airlines. Pilots wishing to apply for these positions typically have their Air Transport Pilot’s Licence (ATPL).
