Sir,
I would like to modify a bit in my above reply. I am well aware of the nitty gritty of telescopic fare advantage. (Credit goes to the experienced bloggers of this website).
I was just trying to reply to the concern for the fare benefit as requested by the original blogger.
The...
more... choice of forcibly travelling in a lower class isnt the concern of the original blogger. He was rather interested to know how he could avail the maximum benefit.
Thank you for your correction.
Regards.
