Why is it bad to go out side seniority
Seniority system is the glue that holds an airline together, it's the only reason pilots stick with a particular airline. Once you have it you seldom want to give it up. If Virgin wanna go outside the seniority list it's a very slippery slope especially when Virgin pilots are already looking elsewhere due to hugely expired EPAs !!
The biggest problem with Virgin are the unions.... or lack of !!
