Respectfully disagree as you're comparing the surface to the size of the object, so it definitely matters.
Here's some math:
Average Earth diameter: 12742kms + 10km
Average airplane surface area = 500m2
12752^2*pi = 510,865,389km2
Surface flight/plane = 1021730 planes
Starlink orbit height = ~500km
Surface at orbit = ~551,712,377 so ~8% increase (which is non-negligible)
Average Starlink satellite surface area = ~7m2
Surface LEO/satelite = 78816053 satellites (77x compared to airplanes)
Daily flights 50k-100k. Total number of satellites <20k.
And this is only for Starlink LEO. If you go for higher orbits the surface grows substantially. Also satellites have predictable paths, altitudes, airplanes maneuver and turn, gain altitude/lose altitude. They gather around points (airfields) etc...
