The best job in the business is without a doubt a manufacturers Representative. Good expenses, stay in the best hotels, car or car allowance and the salary isn't to bad either. Downside. Putting up with all the gripes from the customer. Being on call 24 hours a day. Trying to explain why the manufacturer is trying to screw the airline.(in the nicest possible way)Trying to explain to the manufacturer why the airline is trying to screw them(in the nicest possible way).
Not a job for everyone, but someone who is well experienced in all aspects of the aircraft. A.C.X.R. AFGS. and does not mind being away from home for lengthy periods in some delightful as well as dumps, it can be a rewarding job.
Believe or not it is seen as a prestigeous and respected position by some airlines.
