I totally agree about doing flightseeing if time and finances and weather permit. We just went out with Rust a few weeks ago to Katmai to see the bears. That was a great experience, but it wasn't cheap. I'm thinking close to $1000 for the 2 of us. The Rust people did a great job. I would caution that the planes are rather small, and the flight is about 2 hours each way. If you're over 6' as I am it may be a bit uncomfortable. I could hardly move after the return trip.
