My mom is extremely picky. When we fly together, I go for a choice of whatever they have and she pre-orders the bland meal. If I need to trade something with her, I will. But I always try to get her to grab something to take on. Sometimes there will be something in the snack basket she likes too. If I ever take her overseas, I will definitely be packing some stuff for the flight. She will pick at things for 4 or 5 hours when we fly to the other coast, but I don't want her starving for 10 hours.
