In the same way as I detected a lack of French/UK origin below deck workers on cross-channel ferries over the last 3 decades, airline pax are not all blind. . . lack of PA's in the local lingo etc. . . pay for SAS , get flyygawdknowswhat airlines. Sad that aviation is going that way . . . anyone with some authority to stop it is either not interested, or is in someone else's pocket, for sure it is not merely ignorance of the situation.
