We took an International flight from Atlanta to Rome in June 2016 and I requested a gluten free meal from the Delta website. We were flying Delta Comfort Plus, which is their term for their extra-leg room seats, but it also includes free booze. Score!
I did receive my gluten free dinner, a gluten free breakfast, and even a gluten free snack!
First of all, it's airline food, so my expectations are low; however, they did a pretty decent job of keeping me fed.
Dinner was a tasty (and hot) chicken dish with veggies, salad, fruit, and a rice cake. My son is a fan of rice cakes (yuck), so I passed that to him. There was olive oil for the salad, but not salad dressing.
At snack time, the Normal People got ice cream and pretzels. I got an apple. Still, points for thinking of me at all.
Breakfast was a gluten free version of the frittata that the Normals received. I am not eating eggs right now, so I skipped it, but it would have been a good offering for someone who can eat eggs. I was not given a yogurt (probably their gf meal is the same as the dairy free meal), so I stole my husband's yogurt.
