Sorry but you will need to use the correct wordings because it doesn't mean anything for us at the moment. On AF, Economy and Premium Economy are 2 distincts classes of service (different seats and amenities). There is no "premium Eco standard" or "premium Eco bulkhead". In Economy, some seats are sold as "seat plus" for a fee because of extra legroom (bulkhead, exit rows, upper deck on the B744). In Premium Eco, there is no seat plus.
