Yes, I have done this in the past when I didn't have a printer in my hotel. I would check in 24 hours prior to take off and would just walk up to the quick-checkin computer at SouthWest and reprint my boarding pass. Or you can talk to the ticket counter agent and have her print it for you. I mean should you be penalized if you did the checkin 24 hours before but lost your printed boarding pass during that time? I don't think so. I do think that YOU should be the only one allowed to print the pass.. but I dont know how they could ever enforce that rule.
