Thanks for the link. It was very helpful.
I was wondering whether there will be a place to enter my Delta information when I purchase my SAS tickets. So far, the SAS website won't let me do anything as it thinks I am a bot. I called SAS and was told it was a known problem. I followed the suggestions given and still no luck. A wise person here said to try my phone and it seems to work. I have one more question I will post in a different thread before I purchase.
