Hello All
I am new here.
I am planning a trip from Caribbean to Asia sometime in September or October 2023. It would be a long journey of 30+ hours with a few stops.
I have sensitivity to gluten and dairy. I would like to know which airlines caters to such food restrictions? I know that most major airlines offer gluten free meals and vegan meals, but they don't offer a combination. If I order the gluten free meal, it could still have dairy in it. If I order vegan meals, it could still come with bread and pasta made with gluten flours.
I am not vegan. I am ok with eating grilled chicken (no buter used) and steamed veggies. Is there any special meal on flights that offer this kind of food?
I can fly either via USA or via UK and then make more connections, so I can choose from a wide range of airlines.

Just wanted to ask here which airline in your experience would be best suitable for gluten and dairy sensitivities. I had flown Lufthansa on this route in 2017 and I barely got to eat anything. Thankfully for one of the meals,, a first class passenger had ordered similar meal and didn't want to eat, so they gave it to me. For the next meal they gave me 2 bananas.
I know i can take snacks with me, but this would be a very long journey and I will need to eat meals.

also I am not sure, if this is the right forum to post this to, as I am not specific about any airline.

Is there any way this issue could be addressed to airlines in general. People travelling in economy could have sensitivites too. Aand i am willing to pay for special food.

Thanks.
