WChiCC,
My flight's booked on an A340-300 out of Chicago. When I check the reservation, the chart shows one cabin, 7 rows in a 3 row, 2 seat configuration. The A340-600 shows 9 rows, same configuration if I were to book the JFK 600 flight .So, I don't understand why the row 6 on the A340-300 could offer a more horizontal rather than angled flat seat since there is only one cabin and row 6 is not a bulkhead seat.
Many thanks again for more information.
