BASSA haven't got any exemptions so far. All the planned changes to EG300 were agreed at the BATUC, which BASSA did not attend. Lets wait and see if they actually manage to achieve anything other than a face saving change of name because they're already trying to claim the BATUC changes as a victory for BASSA.
Now if you want to compare BA crew to LH/KL/AF then why do you have so much more sickness than them?
