Thanks, for the assistance.

In terms of your answer to question 3 - the ITA software can give a breakdown of taxes and fees for any route taken (perhaps with stopovers). I wonder if this type of ITA functionality can be incorporated into the a future version of the KVS tool - so I do not have to go to 2 separate software programs, to figure out: first, the fare for a given fare basis and booking code, and then second, find out the true fare, when taxes and fees are taken into account.

When I had looked at this E fare on the KVS tool, I was speculating that the taxes and fees would add up to approximately $100 - which technically is the case - but the $300 surcharge brings up the fare so much that my relative now has to think of other options (she wants to go to DEL from YOW in early March for a month - using the cheapest fare which will earn full Aeroplan miles - she has no issues with routing or stopovers).
