Yeah that's what called exchange of information and that's what your supposed to do here, I ask if I don't know anything and when I comes to know about the things I post here what's wrong in this, it's not other way around.
Why not we do one thing, let's wait and watch and If I am wrong, I am not gonna post anything ever on this blog site and If you are wrong then you do the same.
Well as I said I post what I hear, I have heard from a friend of mine who works in Jet saying IR is must, so i posted that and when I saw people saying they have confirmation from the HR I deleted my post, may be my friend was wrong.
