I am trying to book ticket for 11-Feb-2013 and today is the opening day for the 120 day window. I am surprised to see that there are only 3 seats available in AC 3 tier (LJN - SC). I am looking for lower seats for senior citizens and I am not getting the lower seats. I am wondering if there is a different quota defined nowadays for online booking. Can someone help me understand how this entire thing is working? It is hard to believe that so many people are doing booking in advance on day 1 of the window.
