I strive to arrive by T-30, and if I don't, I'm late. The times I've reached a pushed back plane has been between T-30 and T-15. The difference between reasonable and DYKWIA behaviour is the absence of toddler chest beating if I failed to get on the plane.

Something to consider about T-15....if the entire plane shows up at T-15 the plane goes out late. It's the last opportunity to board and should be used as a cushion for flat tires, accidents, acts of God, black holes - not the time that I want to spend watching my football team in the bar
