I would like to know if the air in airplane passenger cabins is filtered and recirculated , or is fresh air drawn from outside and warmed up at higher altitudes. I’m flying domestically next week and knowing the answer would help me decide whether to cancel, even though I would lose my cost for the ticket.
What airline? The major carriers are dropping fees for canceling through March 31. You don’t get your money back, but you have up to a year to use it in most cases.
Airline filtration varies.
The Cabin Air circulates through HEPA Filters and is refreshed every three minutes. If you are concerned, open the Air Nozzle above your Seat that feeds fresh outside air towards your face.
The Airlines are ramping up their Cabin cleaning between Flights, disinfecting surfaces that are touched the most like Armrests and Tray Tables.
DO NOT touch the Airliner Safety Card or Flight Magazines in the Seat Pouch. They are as dirty as Restaurant Menus.
