Is train me ltt to et around 100 seats aval ho jate hai charting ke wakt. Agar ltt to et ka pax cnf tkt cancel karata hai, to wo sab seats aval reh jati hai jo charting ke wakt use hoti hai. Wo seats charting se pehle use bhi nahi hoti hai. Seats mostly S4 me hi allot hogi aur rarely S14 me allot hogi.
