Sorry - got that mixed up with another plane. But to tell you about the really best seat I had on an RJ 100:
I had a seat in first row of economy class (that was on Crossair Milan - Zurich) and somehow the bookings must have changed last minute so they had to change the curtain. It was in front of me when I boarded tha plane and after I sat down, they put it two rows behing me. I never asked or complained and enjoyed my business class meal and treatment (it's a short flight, but anyway...) :-)
