If Cathay Pacific deploys 77P to YVR, the business class seats will be in a recliner in 2-3-2 configuration with 12.1 inch 1280x768 IFE screen, it will be very disappointing if you sit in a business class middle seat on a 77P to YVR. The economy class seats will be tighter than those on 77A/77K with a smaller outdated 8.9 inch 1280x768 IFE screen than the 11.6 inch 1920x1080 screens on 77A/77K. They need crew rest curtains for the crew to sleep. They needs extra fuel tanks to fly to YVR.
