seat plans are available once you have booked... you can use them to select seats.
I flew with them last year, on the 734. front cabin (nok+) had three rows, 34' pitch. but 2+2 seating (so nice and wide). take row 1 for better leg room. row 2 and 3 legroom was extremely tight.
coach is something like 30'? it seemed very very tight. for the extra couple of dollars, nok plus class is well worth it.
