I've had the same problem today. I got my e-mail message reminding me to check in via the web, but when I tried I got a message saying that web check-in was not available for my ticket. I called NW and the agent indicated that everything was fine with my ticket. I too am wondering about the dreaded SSSS. Oh well, as Elaine said to Jerry on Sienfield when Jerry was worried about what may have happened at the dentist while he was gassed up, "so you were molested a little bit, big deal"
