yes, and with these carriers flying into the airspace of the more security conscious countries I do sometimes wonder why we bother.
What? That makes no sense whatsoever. If your own cockpit is secure, then wonder no more about it and do bother. Besides, as pointed before, be very aware that international airlines on this area (Latin America) do follow the procedure and do bother with the legalities of it.
Get your facts together before posting nonsense
