Flying, under the best of circumstances, can disrupt regular meals and make it challenging to eat healthy. Add in delays getting off the ground and uninspiring choices in the air, and you may find yourself quickly getting tired, unproductive and cranky.

To make the most of your valuable time on the plane, you’ll need go-to healthy travel snacks, such as a dose of fiber-rich carbs for some much-needed brainpower. You’ll also need to be ready to impress as soon as you step off the plane. Protein-rich foods will help sustain you until you can get a real meal.

Just because your favorite smoothie won’t pass TSA inspection doesn’t mean you can’t have healthy snacks for the flight or your final destination. These five convenient travel snacks can live in your laptop bag or favorite carry-on for days. Stock up once a month, so you will always be prepared for that last-minute meeting in New York or D.C.

Picnic in the Air
Perfect for long flights, GoPicnic meals require no refrigeration, cooking or utensils. Each meal includes some form of a protein-rich food, such as hummus or tuna, along with things like plantain chips or trail mix. They come in a variety of flavors, including vegetarian and gluten-free options.

Jerky (Beef or Not)
Natural jerky brands like Krave or vegetarian options like Primal Spirit can transform this convenience-store staple into a true health food. A good source of protein, this shelf-stable snack is perfect to balance out the banana you grabbed with your coffee.

Edamame, Anyone?
With 130 calories, 14 grams of protein and 8 grams of fiber in one quarter-cup serving, dry roasted edamame can keep you feeling satisfied for hours. Choose a lightly salted variety and mix it with almonds for your own trail mix. You can also try such flavors as wasabi-toasted-onion for a snack with a kick.

Protein in a Bar
Not all protein bars are equal or even as healthy as they promise. Look for natural varieties with at least 10 grams of protein, as well as options that are lower in sugar. Luna Protein can halt a chocolate craving while an RXBAR and a piece of fruit can easily serve as breakfast when you’re in a hurry.

The Power of Beets
Move over kale, there is a new healthy chip on the block. Trader Joe’s sells deliciously crunchy beet chips in convenient, single serve pouches. Made of just beets, they are much more nutrient rich and satisfying than the average vegetable chip.

Don’t Forget to Hydrate
To really stay on top of your game, make sure you get plenty of water on your flight. Bring an empty ecofriendly water bottle with you to fill up at the water station by your gate. Well hydrated and well fed, you’ll be able to use your time in the air to clean out your inbox or catch up with your favorite podcast.
