After looking at the thread I have the following requests:

1) Show fuel surcharges column(s)
2) Note base fare (domestic) does not include 7.5% sales tax (now inlcuded in total)
3) Add business and first class filters
4) Parameterize url so bookmarking can be set up
5) Possible Issues with some routing displays (need some examples to test)
6) Fare Pull from our Database Issues
---- a) Not enough fares pulled (500 default by PPM now)
---- b) Doesn't return short haul higher PPM fares that could be used for long mileage routings
7) Default Guess at departure airport by IP annoying
8) Booking Code Filter
9) Departure Date Filter
10) Don't reset the filters on each query

We are probably going to only make one more pass at this for a while so those that don't suggest shouldn't complain ...
