I've been doing a lot of traveling lately, and I'm always looking for healthy snacks to take with me on the plane. I like to use Gate Guru to locate what my options are - they list all food locations by airport, then by terminal. Whenever I see a Cibo Express, I head straight for it. They have all kinds of vegan friendly snacks, including Divvies vegan cookies in several different flavors, Amande almond milk yogurt, Sabra hummus + pretzel chips (one of my favorites) and vegan chocolates/candies.
My two most frequented airports, Chicago O'Hare and NY Laguardia both have Cibo locations, which I am extremely grateful for!
