In-flight Instant Oatmeal

Bring a pack or two of instant oatmeal, a little pouch of nut butter, a baggy of seeds and nuts, and maybe pick up a starbucks banana. When the flight attendant comes around with tea and coffee ask for hot water and an extra empty cup.

Bring a spoon or find a single-use one at the airport.

Ive also done this during a layover, getting the hot water and cup from starbucks (free with purchase of banana).

You could also buy an oatmeal at starbucks without the water and go the flight attendant hot water option.

Many ways to make this work!
