Many reviewers really sleep on how effective the Adaptive Noise Cancelling is on the Studio 3. They just sit in an office and compare it to the Bose QC35 II and Sony 1000XM2. Many don't take into account that the Studio 3 is ADAPTIVE ANC which means it adjusts automatically based on the noise it's picking up. On a plane, the noise cancelling is very good and you will have no problem with the noise from the plane. Just make sure you have the latest firmware.
I felt when Studio3 came out there was a constant hiss in the left earcup but with the latest firmware update it’s gradually dissipated across both earcups so it’s less noticeable. It actually has excellent ANC. Still not sure whether my first unit had defective clamping force or if they’ve adjusted it since then but I couldn’t get any isolation out of the Studio3 due to the lack of a good seal which impacted my early impressions.
