The KLM service on european routes is very good. The FA's are very nice and friendly. seat and legroom is average or above. The food is good, but not too big. before the meal you will get hot towlels or refreshing towels (it depends on flight) The 737 are very clean and you cant see that some of them are from the 80's.
ANd there is no doubt, you will get a flightdeck wisit, and it will may last for about 20 min's. The pilots is very friendly and tells you a lot, so i will guess that they let you take some pictures. (i don't think any jumpseat landing will be able, bacause that seat is use to store different stuff. Clothes etc..)
you should look forward to your flight.
have a nice trip
