Hi @Sara, we have a handout with healthy snacks HERE for ideas and inspiration.
In terms of airplane food specifically, it’s possible to carry hard fruits and vegetables, but you must make sure to consume them before landing wherever you’re going. Most countries don’t allow fresh produce when entering, so you have to consume them before reaching customs. Here are things I’ve taken with me on the plane before:
apples, cucumbers, carrots, celery. On longer international flights, I’ll carry an avocado (I ask for a spoon and just break through the skin and scoop it out)
olives in a small container
homemade trail mix with roasted, salted nuts (cashews, almonds, pistachios, etc), dried raisins
for my kids, I’ve packed homemade popcorn and rice cakes
for protein, I’ve packed natural turkey jerky or biltong’s (available at Organic Foods & Cafe). These help keep you fuller longer because it’s high in protein.
Another option is to purchase snacks once you arrive. Before I travel, I’ll research the area to try and find nearby organic markets or supermarkets with organic sections. My first stop is usually a healthy shop to stock up on healthy food and snacks. Things like squeezable nut butter packs, dehydrated seed crackers, dehydrated mungbean/green pea crackers are things you can keep on hand as well that don’t need refrigeration.
Hope these ideas help!
