I have to book 2AC or 3AC ticket (for two persons) in Vibhuti Express for Varansi- Durgapur for date 19.04.17. 3AC availability is showing as GNWL/AVAILABLE. What does this mean- are seats available or in waiting? Will I get confirmed seat or waitlisted? Also, 2AC status is WL-1. If I book in 2AC, what are chances of confirmation? Pl. reply.
