Sorry for the delay in replying...using the triple 7 for capacity on LHR from YYZ - and I suspect to bring us up to par with BA's IFE, as some of the 767s and all the A330/340s on the run still only have main screen in the econo cabin...tonight for example, the LHR run will see an A330, 767, 77W and 77L heading out...
Also find the 777s plying the Asian services...eg NRT and HKG, although the A340-500 still runs into HKG too - for now...
