First Class and Business Class meals are double wrapped in real chinaware and sealed with kosher certification tape. They are then sent to the airline food service caterer and served in this fashion to the traveler. After onetime kosher use, the china is cycled into the airline’s regular stock of chinaware.
Would the kosher caterer have to dunk/immerse this china in a mikva first, as is the case with ordinary newly-purchased dishware?
(Yes I'm aware that some are lenient regarding glazed earthenware, but let's leave that issue aside for now.)
