Thank you for following my blog and wishing happy journey to my son and daughter-in-law. Now the final position is as follows.
The duty TTE has very kindly allowed my son to utilise a vacant 2AC berth in the same HA-1 coach which he will formally allot in my daughter-in-law's name at Khandwa Jn. I have advised my son to request the TTE as to how to get the refund of difference of fare. I hope this blog will guide the members of IRI in similar situation, if however, arise to them in future.
