This is not related to 'cabin crew' because I have my own customized safety message
My mistake is about jetway. I meant stairs not jetway. To move stairs I use AES menu.
I wanna thank for fast responses. Thank you all
If you watch Froogle video you will notice what I'm talking about.Announcement starts in 11:20.
And also I noticed that my jetway is not moving when ground marshaller tells that they are moving the jetway!!!!
