Forgive me if this is old news, but I just found out and thought I'd share From Southwest Airlines website: Check In and Print Boarding Pass Great News! Now you can check in online and print your boarding pass beginning 24 hours prior to your scheduled flight! That means no more waking up at midnight to get your boarding pass! Much better!! I'm flying on New Years Day, and will be attending a wedding, on New Years Eve. I was wondering how I was going to pull off checking in. At Midnight the reception will be in full gear.
