Highly recommend the Museum of Flight for watching the Blue Angels. Great views, no hassle.
The museum is all geared up to handle the crowds and the event is really well-run. Tons of parking (YAY), lots of friendly staff and volunteers. The usual front parking lot is closed to cars and tents and chairs are set up in that space.
We got to watch the show comfortably in the shade, restroom breaks just inside the museum (along with AC), traffic and parking completely a non-issue. It was the BEST.
Oh, and the Blue Angels were pretty cool too. They take off and land right in front of you. You can't get any closer than that. The pilots waved to the crowd as they taxied. They flew over the Museum of Flight a couple times during the show, and we had a clear view of the skies during their maneuvers. Just before they landed, the Blue Angels raced down to the museum before swooping off to the side. Absolutely exhilarating.
Not front row seats to the show, but for the ease and access, I'd 100 percent choose the Museum of Flight to catch the Blue Angels again.
I was waaay underlensed, but since when has that stopped me from taking a million pictures?
It was our first time catching the show! Two years we were out of town, two years the show was cancelled, and before that, I had one toddler or another who would have been terrified. Now those kids are big and they LOVED it.
