You have no way to know whether the plane has been inspected hundreds of times in a year, or none. You haven't a clue whether the airline has chosen to carry hazardous materials under your feet. There are no cleanliness standards. Tray tables, blankets and pillows don't have to be sanitized. If a passenger plane were grounded and turned into a restaurant tomorrow, there would be far more health safeguards than for the plane in which you may be captive for hours.
Airlines respond to money.
You have it, and you must refuse to give it to any carrier that does not measure up. Put it out of business. Though the federal government collects the data, it refuses to make any comparative analysis. Always ask what kind of aircraft you will be flying. Avoid traveling in storms.
