The gravitational acceleration at the cloud tops of Saturn is similar to that near the surface of Earth — 10.4 m/sec2 for Saturn, compared to 9.8 m/sec2 on the surface of Earth. Thus, it turns out you would feel about the same weight in an airplane flying through the cloudtops of Saturn as you would feel on the surface of Earth. If you flew deeper into Saturn’s atmosphere, gravity’s pull would increase and you would feel heavier. Your weight depends on your mass and on the local acceleration of gravity. Your mass is the same no matter where you are, but the acceleration of gravity can be different. Therefore, your weight depends on where you are in the Solar System. For example, your weight would be about 1/6 as much on the Moon as on Earth because the acceleration of gravity is six times less on the Moon. Your mass, however, is exactly the same on the Moon or on Earth.
