sirwa, I appreciate you fly lots and lots.
However, there are several reasons why you should still pay great attention to the safety brief:-
- Not listening sets a bad example to other passengers
- You will probably fly several different types which will quite possibly have different procedures
- Especially when sitting in an exit row, the cabin crew will want to know that you have been paying attention and will know what your duties are in the event of an emergency
- Safety procedures do change from time to time - if you don't pay attention, you won't know when they change
You don't say whether or not you check the safety briefing card - do you, for example, rebrief yourself on the brace position? Do you know which exits cannot be used in the event of ditching? Will you be expecting to see overwing slides? Do you know how the recommended brace position changed after Kegworth? etc. etc.
I for one would like to know that everyone on board pays attention and is as well briefed as possible because, when I am flying as a passenger, my safety depends to a great extent on their performance in an emergency.
