Onboard space constraints, limited convection ovens and a major lack of ambiance all detract from the enjoyment of skillfully prepared in-flight cuisine. But the parties who provide airline food won't let fliers' dining experiences become subpar.
Do you crave Biscoff cookies or Terra Blues potato chips? If you do, you're probably a frequent flier. I travel a fair amount and while some airlines offer decent snacks, more often than not they are sold out or not available by the time they get to my row, so I find it's best to be prepared.
