Luke - times have changed and standards are slipping but aviation is a pretty conservative occupation, even today. This thread isn't about PPL training though is it? We're talking about prospective airline employees who may be selected or even sponsored by their future employers to undertake the training and/or student pilots who aspire to work for those same companies themselves one day. It's all about mind-set and attitude - presentation, professionalism, discipline, responsibility, attention to detail. The big schools require their customers to wear uniforms - it's contractual and should be non-negotiable but often overlooked yet, should be seen as possibly the only meaningful way these commercial schools can really help their output get an advantage in terms of employability. And yes, I wore jeans and a t-shirt when I was doing my PPL but I already knew how to dress proper by then anyway
