ahhhh thanks,
We use Google Sheets for all of our Fly Vegas stuff. It is fast, easy and allows pilots and anyone on our website to "view only" and they see changes in real time as those sheets are updated. Google Sheets allows us to import data from other Google Sheets as well so all of our aircraft finance sheets are linked to our Master Ledger and when we add a new entry to any aircraft log sheet, the data in the Ledger adjusts accordingly.
We track the history of every airplane from day 1 and include all service intervals, pilot landing rates, who flew the aircraft when, etc. I know FSA does pretty much the same thing in the aircraft data page but our sheets give pilots and admins a quick "full page" view of what's going on. Many people think we are just bat crap crazy to keep manual financial records but a few of us are bean counter nuts AND our cross check documents have exposed a few glitches in the FSAirlines system we were able to point out that you have since fixed.
I tried to narrow your troubleshooting down as much as I could, not sure what else I can do now but if there is something, please let me know and I'll run any test you need. Nothing else going on with most of the world closed down..
EDIT: Oh BTW I tried it without the fleet assignment and the pricing issue remains so it's not tied to that. The random numbers don't even match for return routes to the hub either. KDTW-KSPI is showing $902 out and $823 back. The actual standard price is $94. FYI the non-priority package rate for a single 441 package KDTW-KSPI is $661. So maybe somehow the package system is involved? 661 is closer to 902 than 94 is LOL
