"P.S. Airlines that don't send applicants to the DLR don't give a toss whether you have passed, failed or didn't sit the DLR test......"
I'm not so familiar with the expression "don't give a toss". Do you mean that if the airline, e.g. Air Berlin, doesn't require a DLR test, they don't care if you have taken/passed/failed the test?
And I just bring my question up again: Are there any DLR tests in Austria and Swizerland also, or are they only for German airlines? If not, are there any tests like the DLR in Austria and Switzerland?
