I have booked tickets in Pothigai Exp [12662] on 14th April 2015 from Tiruttangal[TTL] to MS with boarding at MDU. It seems MDU is under pooled quota [which was in waitlist during my booking time] and TTL is in General Quota which is confirmed. I have got the confirmed ticket. Just to confirm whether it is ok or later they will say as no show when I dont board in TTL. First time I am seeing that any quota can be used any where
