I refuse to stand in a line -if there's a queue at the gate, I will take a seat by the gate area until it's quiet. I therefore try to time it so I get to the gate about 2-3 minutes before boarding starts, so I can position myself in front of the podium ready to get on. I also don't like having to ask people to move to get into my seat. So it's either first on or last on for me!
