Biased to your comfort level or biased to your complete ignorance of airline operations?
A 14 hour flight takes as long to brief for as a 45 minute flight: about three minutes. Even if I am doing a 14 hour flight to Seattle all I need to know is the weather in Seattle, Vancouver, Kuwait and Shiraz, plus a quick look that LIDO has confirmed for me that the ETOPS airports are Adequate.
Get out your stopwatch and time me.
