I like the old boarding system of rows 35 and higher, rows 30 and higher, etc. I can understand why airlines board by zone now ($$$) but it just doesn't work as well, as we can all see. If airlines make X dollars by selling a better boarding zone but lose Y dollars on a longer boarding time, is X>Y? Hmmm...

Southwest is the opposite. They got rid of the line campers with the A-B-C numbered boarding system. Actually they've always had a numbered boarding system but they didn't care if 1-30 boarded in that exact order, which led to people camping out, first to get a boarding card, then to sit in the group of 30 to board. The numbered posts you stand next to for a short period of time works great.
