Montego Bay to LGW, in Upper Class. I have flown Upper Class before and been happy with the service, but this flight was, frankly, a disaster. Check-in at Montego Bay was chaotic, with no dedicated Upper Class desk and certainly no fast-track security lane. The lounge (run by Air Jamaica) is little better than the general departure lounge in the main airport building, and the only freebies on offer were tepid cups of tea and syrupy glasses of Coca-Cola, together with a bag of plantain chips. The lounge manager moved us to the gate a full 20 minutes before it was necessary, meaning that when we arrived at the gate we had to stand up (there were no free seats) while the plane was readied for boarding. Perhaps there was a failure in communication? It was simply idiotic. Boarding proceeded badly, and there was no priority system for Upper Class passengers - everyone just boarded at once. Once onboard, a completely unexplained 2-hour delay annoyed everyone on board, a situation compounded by the fact that the air-conditioning system was broken. The inflight entertainment system (Nova) was clapped-out and completely outdated, looking positively pitiful next to the business- class offerings of other leading airlines like BA, Emirates, Qatar and Cathay. The food was even worse; dinner was grotesque and breakfast - a bizarre concoction of curled, wafer-thin melon slices drizzled in a miserly amount of astonishingly revolting yoghurt - was abysmal. On the plus side, the cabin crew were reasonably friendly and attentive, and the beds were comfortable (even though the design of the Upper Class suite is bizarre). On the whole, very disappointing. Other than the flat bed, I don't see that I got any extra benefits by paying £1000 more for each ticket. Why bother upgrading from economy?
