When you sit in your seat and during take off or landing you can literally smell the fuel or its exhaust in the cabin, you have to be pretty dumb to think that the corporation that designed the aircraft has your best interests at heart ... or that the airline company that now owns the aircraft will say anything about it.
Some airlines are better about it than others but I've been on some smaller aircraft and it's amazing the sense of the air quality when you're in your seat inside a sealed air compartment and you can still smell the engines.
I noticed that too! I went on my first plane journey a few years ago (Airbus A320 neo) and was concerned about the very kerosene-y smell while taxiing, but no one else seemed to be bothered by it.
Turns out the cabin air is just bypassed from the compressor, and when the plane is reversing, the exhaust goes back into the compressor and thus the cabin (my terminology may not be accurate). So it means the airplane manufacturers won't even bother putting a proper air filter in their planes.
