The best way to do it is to make the listing in the ID-90 site, in about 2-24 hours later you'll get a listing res # like normal in an email from delta. Take that to any agent and swipe a credit card and in an instant you'll get your paper tickets.

I have done Alaska tickets from the counter in SEA with a delta agent before, but most locales they are not trained to do zed's from scratch anymore, hence the id90 listing/ delta res step.
