enter the building and keep left for the reception
Just to the left of the reception desk (between reception and the gift shop) is a long hallway towards the cinema, and you queue there for the next tour. You can also tour the downstairs museum while you're waiting for the tour to begin.
You can buy ticket in the building without long line. While waiting for your tour, you can take a free walking around exhibition hall and upstair open deck, where you have a better view of the Boeing site.
Once you go inside the building their will be a reception desk
