Well I've got bad news for you because most airlines have similar policies to FR.
These days pretty much every airline,'s default policy is agreed with the regulator,.and that's (regulator dependent) something like load fuel needed for flight from departure to destination plus a small buffer (maybe <5%) plus enough to divert to a nominated alternate plus enough for another 30 minutes flying....
The days of the captain routinely asking for an extra tonne (shorthaul) or 10 tonnes (longhaul) "just in case" has gone, unless you have good reason (e.g.thunderstorms in the forecast).
