In IR there is no definite connection between the quality of service and pricing. A pax in a regular train with 1000 Rs fare usually enjoy better facilities, punctuality than Suvidha/PT pax on same route with 3000 Rs fare!
.
More over, the flexifare introduced in HS is a very much diluted version of flexifare in Raj. In HS 50% pax pay normal fare and in Raj only 10% pax pay normal fare. In HS only 10% pax pay max. flexifare where as in Raj 60%/50% pax pay max. flexifare.
