I always liked Bullitt and the scenes at SFO. Plenty of Pan Am 707’s and a PSA 727’s moving around the ramp even some shots inside the Pan Am 707 cabin. Awesome movie if you haven’t seen it.

The first clip has the 707 enterior and the second clip has the footage on the ramp/taxiways.

That was a great movie
