Flying is an old boys network and pierced ears are a real no no. I myself couldn't give two sh*ts what you look like but to those who are hiring it will make the world off difference.
Essentially as bloke wearing an ear ring/stud your saying you have an alternative way of doings things and your quite happy to sway from the norm - with first glance you've failed your psycometric tests - be very careful.
On your days off do as you please, but never
, ever wear a stud or ring into an interview or at work as a pilot in an airline.
good luck matey!
