Thanks. Yes, I'm well aware of how airlines control award inventory, and that they may release less to partners. What I didn't understand was:
- Why did the entire schedule for this flight disappear from Google Flights, despite that AF was still selling it?
- The O inventory that EF shows should be the space that AF releases to partners; I know that Flying Blue will show more. Since EF consistently showed many days of O space, VS should see it.

Anyway, the mystery has resolved itself today, as VS now sees tons of space again, and the flight has reappeared in Google Flights.
