BARBIL TOURS · Seattle
A private car and guide collect you in Seattle, spend about four hours at Boeing Future of Flight in Mukilteo and four at the Museum of Flight on Boeing Field, then drive you back. Pick it to see Boeing's present and past in one day without driving I-5 twice, knowing the factory tour itself depends on availability.

BARBIL TOURS added this private day to Viator recently, and it has no reviews yet. The plan is simple: pickup in Seattle, about four hours at Boeing Future of Flight in Mukilteo, about four at the Museum of Flight in south Seattle, then back to town. Eight to nine hours in all, in an air-conditioned car with bottled water.
Now the line that matters. The listing offers a "Possible unique tour of Boeing Everett Factory (availability dependent)" and says "If possible, tour the Boeing Everett Factory". The factory tour is not guaranteed. If it doesn't happen, your Mukilteo stop is the Future of Flight gallery and the Sky Deck, which Boeing sells for $14 on its own ticket page. Before you book, use the question link on the Viator listing: ask whether the operator will reserve a factory tour slot for your date and whether the ticket is in the price. Free cancellation up to 24 hours before leaves you room to back out.
The price is $1,195 per group of 1 to 3, about $398 each for three, and a 1-to-5 option has its own price on the listing. If the factory tour is the point of your trip, the shared coach guarantees it for $135, and the museum ticket costs $29 on another day.
The guide phones the day before with the time and place. Choose your hotel or another address.
Up I-5 to Paine Field and Boeing Future of Flight.
The gallery, flight simulators and the Sky Deck over Paine Field. The factory tour only if a slot is free.
Around 35 miles back through Seattle to the Museum of Flight. Traffic sets the clock.
The Great Gallery, the space gallery, the Red Barn and the Aviation Pavilion across the bridge, whose aircraft open 11 am to 4 pm.
Drop-off where you were picked up.
★★★★★The Boeing tour was incredible! Seeing the airplanes up close in production was educational and fun. Don't miss flying a simulator in the Future of Flight!
★★★★★[...] The facility tour was extremely informative and the visitor centre was excellent, and gave both a historic and future development view of the Boeing company [...] We hadn't appreciated just how LARGE the facility is [...]
★★★★★The Red Barn was amazing and very interesting. Lots of planes to see and go into. Was a great place to learn about flight and WW 1 and WW 2.
