Working for an ops or crewing department can be great fun and a brilliant way to learn the "in's and out's" of the functions of an airline and is a brilliant grounding for an aviation career, particularly if you are young and keen on aviation.
However it can also lead to opportunities to side step into other departments after a time, maybe even pursue a flying career, and broaden your horizons.
The downside to aiming and working solely for ops/ crewing is that you are bound to peak at some point in the future and you will find yourself with nowhere to go as not many senior positions in ops/ crewing tend to exist as people tend to hold on to those for career duration, particularly ops/ crewing managers although you maybe lucky and yours might just retire or find a better offer - it could be a long wait though. To guard against this trap it is well worth studying other related subjects at college and be prepared to jump departments in the future in order to "get on" if indeed that is what you want.
I speak from experience and I'm sure many in the industry know of the bitter, disappointed, aged and tired ops controller going nowhere, dreaming of retirement and who's body is beyond coping well with the endlessly long night shifts. I for one know of such people and I asked myself, "Is this what is to become of me one day ? ". Needless to say that I side stepped and following the economic decline of the industry, have now left aviation to be succesful in another field, without having side stepped first such a move would have been impossible.
A career ops/ crewing person leaves you with nowhere to run when the going gets tough!
Enjoy whatever you decide !!!
