I have just returned from the Dominican Republic, 777-200 into LGW, Club World. Throughout the entire flight there was no entertainment system whatsoever, not even the map worked. Even more frustratingly, this was just the front Club World cabin only rows 1-4. The rest of the aircraft was fine.
Got the usual story of them trying to reboot – they knew the thing was bust when they left London earlier that day. The cabin boss just came round and said she had given up and to fill in this form which she handed round.
I received 12,000 Avios within 48hrs..
However, questions have to be asked when travelling on a major airline in a premium cabin why such a major part of what they offer fails completely, and I know this is not the first time.
