Southwest's New Boarding Procedures

I just read an article which informs that Southwest is changing their boarding procedures. While they will still have open seating, the boarding passes will now be numbered, which will delineate your place in line. If you're not familiar with Southwest's current boarding procedures, it goes something like this:

24 hours before your flight, you can check-in online. You print out your boarding pass and are issued a letter: A, B or C. I believe that the earlier you check-in, the higher your number is. Obviously A boards first (after the pre-boards), then B, then C. Because Southwest doesn't have assigned seating, you can choose to sit wherever there's an available seat.

With this new procedure, however, you will still have open seating, you will still be assigned a letter, but you will now have to get in line accordingly. I think that theoretically it's a good idea, however, with people like me who are usually running late and have sometimes made it to the terminal with only a minute to spare before boarding begins, it kind of sucks.

At any rate, I'm anxious to see how smoothly this new boarding procedure goes. I enjoy flying Southwest, not only because the rates are reasonable, but because it's very convenient and they go to many places that I like to travel to. Hopefully it won't cause more chaos or delays than there already are.
