What's a good snack for a long flight?

On long car trips, we like to take grapes and peeled clementines. Sometimes we bring celery sticks or raw sugar snap peas. Trail mix is more filling, if that's what you want.

For junk food, nothing beats M&Ms for being sweet and non-messy! I find pretzels to be less messy than chips.

For something sweet, either the Nutella or Biscoff snack packs that come with wafers/cookies and a small tub of Nutella or Biscoff to dip into.

The squeezable applesauce pouches work well traveling.

You can also easily find individual snack packs of seasoned and pitted green or kalamata olives.

Individual snack packs of beef jerky.

I'm diabetic and have several main food sensitivities. I carry food with me always!

I bring trail mix, Goldfish pretzels, Kind bars with protein, baby carrots, a peanut butter individual sachet, fruit leather, and Wheat Thins. They pack down well, don't crush easily, don't need refrigeration, are a mix of protein and some boosts if my blood sugars get low. I can fit it all in a quart sized bag, too. If I know I'm traveling over a meal, I'll also include a pb&j as well.

OMG I was like WHO IS POSTING THIS, are you serious??? and then I read the second line.. OMG.. so laughing hard right now.  

We usually do grapes, an apple or a banana for a fruit option and then trail mix, protein bars and a bag of Flipz (white chocolate covered pretzels) to cover the salty/sweet hunger pang.

This is hilarious!  Do they have some sort of jelly checking machine, or did you have to open the sandwich for inspection?

They roughed it up a bit, tried to open it inside the baggie then asked me to open it. It was silly, but in all fairness it was early on in the new 3 oz restrictions and things were a little chaotic.

 They were crazy. 3 ounces is roughly equivalent to 6 tablespoons or 1/3 of a cup. The sandwich would be impossible to eat with that much jelly on it!  

Roughed it up!  I love it!
The proper solution in this situation is to eat half the sandwich.  Then ask for 3 ounces of milk to wash it down.

Crackers with cheese and maybe some meat to go with. Tides you over. Then some caramel filled M & M's for dessert.

Chocolate chip mini muffins.  

But not bananas that are ready to be turned into banana bread, 4 of them, and then refuse to put the peels in the trash because they are good for your garden, all on a 6 hour flight. I was ready to strangle Peggy. Finally, 4.5 hours in, the flight attendant made her give up the peels. It smelled so sickly sweet. 

I'm still pissed off at Peggy. Where ever she is.
