Maybe it’s better not to ask this one. You’ve likely seen turnover crews vacuuming and emptying trash from the cabin, but what about those tray tables, armrests and windows? It’s probably best if you just bring disinfectant wipes with you, to tell the truth.

The quick turnover between flights means airplanes don’t go through deep cleans as often as you might hope. The FAA isn’t in charge of the frequency or thoroughness of plane cleanliness, meaning the airlines can make their own decisions on the matter.

In general, those in the cockpit don’t eat the same meal (or share food) while they are on the job. It might seem arbitrary, but the guideline is intended to prevent food poisoning. When you think about it, it’s probably best that those flying a plane aren’t constantly running to the restroom.

On international hauls there are crew meals, but not on domestic flights. Depending on the airline and the pilot’s discrepancy, the pilot gets the first class meal while the co-pilot receive a business class meal. Nonetheless, many members of the flight crew opt to bring their own rations for the journey.
