QWERTYUIOP,
I'm not British -but having flown for a couple of English speaking companies and still fly in one with many foreigners I have to say you & I are on equal terms in Europe.
With JAR you can apply for jobs in all JAR contries just like me. In the UK & Ireland the airlines require you to speak English before they will even look at you for a potential employment.
In other european companies they require you to speak their language which is only fair.
As a Brit that's where you are having difficulties as you Brits normally don't speak other languages than English.
So if you are dying for a job in Germany, Scandinavia, Italy etc well start taking some lessons in the relevant language course and I'm sure they will look at you too.
