Vortex, I admire your passion and enthusiasm for Aviation, along with many other people but I would strongly advise, that you do not offer your services for free under any circumstances.
When you do find your first job in Commercial Aviation, I hope (if they will allow you to) you stand
'shoulder to shoulder' with your work colleagues through 'thick and thin'.
Unions fight for workers rights, in many professions throughout the world to improve pay, conditions, contracts etc etc.
If you are offering your services for free, then you are going to be upsetting a lot of experienced, seasoned, wannabee aviation professionals...........Click on the link below.....

Have a think about it, please
