If you checked in, you have a ticket. You might not yet have a printed receipt for your (electronic) ticket, but you have a ticket. The fare basis of your ticket should have been available when you purchased your ticket, but you would not necessarily have had any reason to take note of it at the time of purchase.
Some Coach fares are "instant upgrade" fares; it's possible that you purchased one of those.
