As Mr H says there’s simply no like-for-like replacement. I always set up schedule change and aircraft change notifications in Expert Flyer for my award bookings. But there can be a 12-24 hour delay before they ping me. That may be enough time to try and rescue legs before they get auto-cancelled on some OW carriers, and often quicker notification than from QF, even for QF operated flights. But no way to check ticketing status or any of the other details CMT used to have.
I can only guess CMT had some sort of privacy concerns raised, forcing them to pull the simple web interface and refuse to import bookings with a non-matching email address. At least Trip case allows you to add supplementary email addresses to your account…but it doesn’t play nice with Amadeus. It’s the Sabre equivalent I believe but is pretty bare bones. It is however better than VA at notifying flight delays, fwiw…
