I've flown BA WT+ on 3 trips, New York, Orlando and Miami, each time flying myself, wife and 4 kids in the same class. I can't comment on Air France but I would agree with most posters in this thread, you can't compare BA WT+ to a business fare. WT+ has extra leg room YES, but the service is poor, the cabin feels small and 'confined', you have to practically beg for a drink on longer sectors, the food is not far short of awful and the whole experience, aside from the extra leg room is really very dissapointing. I'm not a BA basher but frankly I think the product is a very poor relation to competitors, others do better for less and with a smile too! I'd pay the extra and go Air France, it's a no brainer, it certainly can't be any worse than BA, who I won't be flying with again if I can avoid it.
