Very very bright chances.
Can wait upto 24.6.2010 for a progress. However bigger progress happens at the time just before chart preparation on the journey date.
@ You can also try out in Tatkal booking as a standby measure which will open on 25.6.2010 @ 8.00 am. (Tatkal too - there will be bright chances).
@ If you...
more... get confirmed tatkal ticket, only thereafter cancel the present ticket and only Rs. 20/- will be the charge and hence full refund.
