You say pick an early time to board. Two issues with that.
First, the time you pick is for check in, not boarding.
Second, if you arrive extra early, you may indeed board sooner, but doesn't that mean a longer wait at the terminal before they let anyone board?; plus there are lots of priority passengers that will board before you (if you're not one of those, which I am not).
I am interested, as I will be departing from there in 3 weeks.
I've seen comments about boarding that if you show up later, you shorten your total time by quite a lot.
