plane travel
As long as it is not straight liquids, airlines can't stop you from bringing food( yogurt might be a little iffy?) through security for the flight. and it can be more than 3 oz. I've flown 5-6 times in the past year and always bring food, no prob.
Also, I would not bring tuna or eggs of any kind to eat on the plane due to the smell as a courtesy to other passengers. I would eat these in the airport, but not on the plane.
