The company enjoys a pay and duty benefit with a :45 min report. Some are more than happy to oblige with a gitterdone at any cost attitude. Flight planning in the hotel room or van just masks the issue at hand. As mentioned, a thorough preflight consumes :45 min. Throw in a couple operational issues, a lengthy MEL and you can easily see that :45 min is not enough unless you cut corners. What's your answer going to be to the NTSB?
Two sets of eyes are critical when looking at the flight papers. The text me if you're copasetic might work in most occasions. There are times when a face to face discussion is more appropriate. I think our flight attendants and passengers deserve better than a haphazard operational attitude when it comes to flight planning.
