The crew at BHX were under the impression that the WIFI was to be on all the 787,Max aircraft and the 738s that have the Sky cabin which is G-FDZT onwards I believe . Having used it on Norwegian before I personally think this is a value added product that leisure customers would use especially on the longer routes down to Eastern Med and Canaries where there is no IFE. I understand from the service providers that it is actually quite an easy install with only a few days of downtime to retrofit the equipment.
