I have an upcoming journey from JP Jaipur to ASV Asarwa Junction on 16th November. When I booked the ticket the status was W/L 9. Now I just received the ticket sms saying the status is RC 21. Is it the final status or is there a possibility that it could change to completely confirmed? In RAC I will get berth details after chart preparation and have to share a seat with some other RAC. But can it be confirmed fully as there are still 2 days left for the journey?
