We're going home to New Zealand in a couple of weeks, and I was looking at the Allergy NZ site which says allergic people should never eat airline food and you shouldn't take such risks when up in the air.
I did have a problem a few years ago with DS1 getting the wrong meal, but it turned out I had been badly advised by the airline staff to order a non-dairy vegetarian meal. Last time I wrote to them in advance and they gave me a special form to fill in and booked him for a medical non-lactose meal (supposed to be fully dairy free). The meal looked fine (no sauces, no cheese, no milk, no dessert!) and it was all ok.
So am I being irresponsible in letting DS1 eat the airline food?? I will take dehydrated pasta meals as backup in case I suspect a problem, and he will have his meds with him. He is also doing well on a desensitisation protocol so is presumably less allergic than he once was.
The only other option I can see is 4 or 5 identical dehydrated pasta meals during the 24 hour flight!!
