For what it's worth, this is quite different from any of my experiences missing a flight, which for me have always resulted in at least a couple hours of additional delay, and on some occasions over six. For my sister, on two occasions it has resulted in delays over twelve hours.
Nearly all of these were due not to a deliberate attempt to arrive at the airport as late as I could get away with though (in general I do not try to do this unless the alternative is getting up unconscionably early, because of my experiences regarding the unpredictability of airplane schedules and the amount of delay that can result from missing one,) but because delays on flights I did make on time caused them to arrive after my transfer flights departed.
This is the public group instrumental rationality diary for October 16-31.
The poll earlier this month seems to be sufficiently in favor of maintaining the current schedule that extra votes are unlikely to change things much, but if you'd really like to register your opinion, you are welcome to do so here.
Thanks to cata for starting the Group Rationality Diary posts, and to commenters for participating.
Immediate past diary: October 1-15
