So we got to Gdansk airport and they had no record of our flight booking. They were very helpful, and it wasn't the fault of the staff at Gdansk. We had to pay extra from our credit card which was of course refused due to suspicious activity (!). The flight was late leaving and we had 30 minutes to rush from one terminal at Schipol to another. The moving walkways did not all work and there are security checks en route. We just made it to our next flight but only because we are relatively fit.. Never again. They give you food on KLM but it was the same on each flight, a strange not very nice sandwich.
