Yo everyone, good morning! So, today I'm sharing this weird experience with all of y'all, it happened for the first time with me today. So, my known folks had a reservation on the 12138 Punjab Mail from AGC to NK in 3AC. Their status was RLWL 7 to RLWL 10. Guess what happened? The chart was prepared at Ferozpur, and there were empty seats available from Ferozpur to Bhusaval (they were in the current availability). Then the chart was prepared at Bathinda, and vacant seats were available as per the RLWL charting up to Khandwa. Charting was done at New Delhi, seats were available in 3AC up to Mumbai CSMT, but our PNR didn't get confirmed, it stuck at RLWL 1 to RLWL 4. I was surprised to see that seats were available from NDLS and our PNR still didn't confirm. As far as I know, current availability only shows up when all other waiting lists are cleared. First time I saw that in a RLWL charting, current availability was only shown for the stations falling under that RLWL chart. Usually, current availability pops up only after all RLWL waitlists are cleared. Today felt like the stations falling under NDLS RLWL had current availability, but the next RLWL charting quota clearance didn't happen, why tho?
