I posted this on the other forum as well and someone there brought up an excellent point that today's United is filled with new hires. Years ago when the union agreed to 45 minutes most pilots had a decade or sometimes more experience in their fleet, seat, and domicile. Today when I'm departing from an uncontrolled airport in high terrain and bad weather with a new hire that may never have flown in any of those conditions, then really 45 minutes is inadequate. Safety should always be first and foremost.
