There seem to be two companies which produce the majority of airline kosher meals. Both of em do a bento box style thing with salmon that I’m fairly sure was caught by Moses himself.
BTW the frozen delivery isnt about Glatt. Glatt only applies to meat (four legged meat not winged meat) and Glatt basically “ends” at the slaughterhouse, long before the Kosher food service company delivers their product to the airline catering company. The rabbinic supervision also ends when the product goes out the door.
To accommodate the logistics of airline catering & the standardized form factors, airline kosher meal packs are all done double sealed at the production facility. The inner seal is basically “safe” for use within the heating devices used on planes but the outer one has to be removed before heating. Thats why the flight attendant always asks if it is OK for them to open it since the heating devices are never kashered.
The stuff one learns when spending shabbat with guys who work in that industry…
So anyway I dont feel bad for this guy and his banana. I’ve had 16 hour flights where I got no meal at all. Yes I’ve since learned to pack food in my carry on.
