I can completely understand what you are feeling Syed.
I too am an out of work Airline Pilot, 2000 hours with 400 turbo prop, lapsed multi and single pilot IR. Lost my job last December.
I'm hoping that it will explode this autumn/winter for us in terms of job offers. Then perhaps next year it will the turn of the low hour wannabees- the ones who I think are a little jealous of our experience. I worked hard to gain my experience.
In my opinion it is not worth renewing a SINGLE PILOT instrument rating just for the sake of being able to apply to a particular airline. We have jumped through the hoops once - why should we go back and jump through them again just to please one or two airlines. The company will renew your MULTI PILOT I/R once you join the airline on an LPC.
It will happen ---wait and see????????????/
