That's a little low, probably, for an established base... But not by much. Switching from Preconstructed lines to PBS increased line holders and reduced reserves by about 10%. Before PBS hard line awards went down to about 75-77% in base, whereas now you can be in the high 80% range and get one. UAL staffs for blizzards in DEN and ORD with earthquakes out West and nor'easter back East, everyday. CAL staffs for CAVU from here to the moon and seem genuinely surprised when IAH gets thunderstorms in August or EWR gets snow in Dec.
