Your flight permission and the associated medical fitness secure your regular income and thus your standard of living for you.
As a flight attendant you are more at risk of being unfit to fly. However as long as you are only "unfit to fly" and not disabled, according to legal regulations, you may be relegated to any other occupation.
We have recognised this risk and created an insurance package to minimise it.
You can live and work in Switzerland or Great Britain, the insurance coverage is provided worldwide.
