I try to just end up somewhere in the group of 5 that the posts designate. If it's orderly, i try to get my spot, but if it's messy then i just settle for within the 5 somewhere - does it really matter if i'm 4 more spaces back getting on the plane?

Also, i have hopped ahead of people who were clumped together and wouldn't move despite my attempts to get behind them but not into the next 5-group. I don't mind getting on first if they wont budge
