Judging by the state of some of the scruffy looking folk one sees at airports these days in pilot's uniforms, sartorial standards do not feature very highly in some airlines.....
But is it really too much to expect a trainee to look reasonably smart during training? Or do some think that slouching around looking scruffier than many a bus driver is adequate?
'Bulled' shoes are an irrelevance; being an ambassador for your airline certainly isn't!
