Beware that there are now two versions of the A320. The last exit row of A320 Vers. 1 is 11, but in A320 Vers. 2 it's 12!

I was booked on Vers. 2 last evening IAD-SFO and had seleced exit row 12, but when checking in I found myself in E-. Lucky for me, seat 11A was free. If I had not checked my seat when olci, I would be in for a nasty E- surprise.

Aaaaarrrrgggghhhhhhhhhhhh...
