BTW, BOM 930 and DEL 790, JFK 725 and EWR 575.
I don't know how IATA calculates these averages (do they take C-claas fares aswell and do they only count the IATA published fares etc.?) and thus won't comment on the averages, but I've some doubts about these numbers.

What I think is that IATA/BSP has the listing of what the travel agents issue, that's how they report their sales.
Coupons go to the airlines that uplift them. From the uplifted coupons, some go to the clearing.
So as usual, and as it always will be, statistics are and will be statistics.
The face value on your coupon is not always what you pay. In many cases, you pay a discounted fare, but that fare does not appear on the ticket.
What is on the ticket is
in some cases what you paid, and in ALL other cases more than what is paid. The face value as it is called, does not always reflect the amount paid.
What I think is that the mentioned statistics are based on face values. Airlines do NOT count with these stats, for obvious reasons. (Although, for some airlines in the past, it looked that way, and that explains their losses....

)
In fact, the real revenue averages are well kept secrets of each airline.
The calculation of the total passenger revenue of a relation is already very if not almost impossible to calculate
exactly, as is the total cost of such relation. That's why cost savings sometimes do not reach the (fysical) target, and why bigger airlines have more difficulties to calculate,and attribute costs and revenue to a particular relation.
