I've never really understood why F/Elites think they have to board first. What sane person actually wants to spend more time crammed into a plane seat? Unless they just want all the people from steerage to see them.
F or not, the lounge is always preferable IMO. Boarding staring with the back rows seems to me a lot more sensible. No delays, no crowding, no climbing over people who are perplexed by the logistics of putting a bag into the OH.
I'm usually one of the last to board and really have no desire to spend more time than necessary on the plane.
