Yes, it should show. Maybe you fell victim to this:

Give it until Tuesday at least before trying to retro-claim...to be fair, I've found in the past that flights can post sporadically when a weekend is involved.
Look on
www.checkmytrip.com too - is the number in it? You want to get it fixed for the return if not. Ask at the desk for them to delete your number and re-insert it if it doesn't show on your BP next time.
