Northwest Airlines Sucks!!!!!

I used to love to fly. I probably will never fly again, these airlines (all of them except Southwest) SUCK. I just finished attempting to on line check in my wife for her flight to Denver. Three attempts, a printed boarding pass and the final screen says unable to complete check in. So is she checked in or not? She has been on the phone with them for about 20 min. and gets an auto response menu that says "unable to complete" and transfers her so a live person who has no idea why she was transferred to her. What a cluster F. I guess we'll go early and try to figure it out at the airport. Boy, am I looking forward to that! My next post might be from a jail cell.
