You have come to the Frequent Flyer Southwest Queen and MAN does this new thing kinda blow.
OK, its not enough to get there early. You will need to either get there early AND check bags OR get there early AND get a boarding pass out of the "secret machines" with your security document (if you are ticketless).
If you are ticketless, you will need to log on to the website and print a Security Document (using your confirmation number) 24 hours before your flight leaves. If you can't do that, you will need to go to the ticket counter and stand in line to get a document in order to get through security. Just having your confirmation letter for ticketless is no longer good enough.
Once you have all your documents you have two choices, either (a) check your bags and receive a boarding pass with an A, B or C on it or (b) find the "secret machines" that are available in SOME airports, enter your confirmation number to get an A, B or C pass printed out.
If you do not do either of the above, you can get there 3 hours ahead of time, be the first person to check in at the podium and still be in the B boarding group (because everyone that did all of the above have already snagged the first 40 places in the virtual line). On most planes there are 40 people per boarding group.
I know cause it happened to me last weekend.
So, since I don't check bags for 99% of my Southwest flights - I am now scoping out the location of the ticket machines in advance so I can snag my Boarding pass BEFORE I get to the podium. Once you have your boarding pass, you don't have to check in at the podium again.
*sigh*
