Not sure of the significance of Fin236 being in YRQ is but, I just walked off of it and, despite my love of the space/elbow room on the old XM J seats, the Wifi was absent/unavailable (despite the QR stuck to the small screen). It's still the "old" interior.
Bad luck after having booked AC142 served by a 788 (it was cancelled). Crew was excellent though. Both sides had a bit of a chuckle when they offered earphones for the IFE that was disabled...
