We got ours in the gift shop, just inside the main entrance. I do not recall the prices, but there was so much history to be seen, I was not focused on the price. There may be an opportunity to check out the Ju-52 hangar next door. In warmer months you can pay to ride on one (or more?) of them. To get there, we caught the train from the main Zurich station to Dubbendorf, there are multiple exits from that platform. The one that comes up and winds to the right, near a roundabout is the way to go. A short walk will bring you to the museum.
