I'm seated in row 21 on an AF 340-300. Per DL that is economy comfort/premium economy, but per SeatGuru it's a standard economy seat. I checked with two different DL Plat line agents, both see it marked as econ comfort (there is a dollar sign next to the seat on their map, not a standard marking). They can't access rows 14-16 at all on my ticket class (V, about as low as you can get in normal ticketing pecking order). Those rows appear to be the real premium economy, and it appears to be a two class flight (Biz/Econ, no First). So, am I in a better seat than the ones further back, or is it the same?
