there seems to be a real issue with booking across all routes - i hardly see any availability across DEL-BOM, DEL-BLR, DEL-COK, DEL-KOL or for that matter any other routes all the way to September. Seems Vistara is either not releasing enough reward seats considering the travel boom, or the reward seats are getting filled in very very fast - my gut feel is that its the first reason, not sure if there are so many CV people with enough CV points to lap up the seats so quickly
