The seats can be filled only if a TTE comes to check the ticket,,, I travelled till EKM but I never saw one.... The issue is same on this train when one of my colleague traveled till EKM 2 days back.. even he was traveling on an RAC ticket and the seats were vacant..... The nuisance of the season ticket holders is such that we cannot board reserved compartments from BNC, KJM etc.... especially the compartments which are adjacent to unreserved compartments... leave alone vacating the reserved ticket to the ticket holder,,,,
