Normally I'd use the search function, but....

I've just booked a ticket on BA680 LHR-IST, in J, on an A320. But I'm very confused about the seating plans. On the BA site, the A320 Club Europe page shows CE as being rows 1-25, or in other words the entire plane is configured as CE.

But on the A320 Euro Traveller page, it shows rows 10 to 21 as ET (in the text description) but rows 9 to 20 as ET (in the graphic.) I'm currently booked in the "exit row" which is allegedly in J. The BA agent who I purchased the ticket from (in Vancouver) explained that econo starts at row 13, and I'm in row 10 (I think.) But I don't want an ugly surprise and find out that I'm actually in the econo/Euro Traveller section, even if it is an exit row. I prefer the width of the "2 seats instead of 2 section" much more than any extra legroom.

So I'd be grateful if anyone could set my straight on just exactly how the plane is configured. 'Cause the BA site is worse than useless in this regard.

Thanks in advance.
