you can't, unless you freeze it after you cook it and keep it frozen till you get where your going

and then re heat it.

You would not be allowed onto a passenger aircraft with hot food in your flight bag. Seafood will deteriorate rapidly and needs to be prepared and eaten as fresh as possible.

This is going to be nasty.

Hot it would just rot and grow bacteria the entire time. This is besides the idea that they're going to let you on the plane with this or that anyone wants to eat yesterday's leftover seafood pasta.

I'd avoid traveling with it and cook it at the place you are going. It's extremely hard to keep something warm for that long without electricity or fuel. Think about food that has been sitting out for a while at a buffet. It's dry and doesn't taste as good food that immediately comes out from the kitchen.

The other answerers are correct - Don't Do It.
