I have 8 CNF seats in 3AC for LTT-ERS DURONTO for 23/12/2014. But seats are distributed among 2 bogies. We are 2 couples+ 4 kids. I want all seats in 1 bay. What to do ? I had booked seats advance in 60 days. After boarding, is it possible to exchange seats with co-passenger or not ? I have no experience of DURONTO. Anybody any idea. Please suggest.
