I know you are disappointed about missing Q-Suites, but QR 777 is probably the best of the 2x2x2 seats in the sky. I can assure you there are far worse J cabins out there.
Unless you are leaving in the next few hours there is still plenty of time for it to change back to Q-Suite
once had to deal with recliner on a CX Regional 773, my god, worse 5hrs flight ever
