This whole thing issue is really interesting.
My DC have no SN. They're just fussy little sods when it comes to food. Flying and getting them fed is a nightmare. It is REALLY hard to get food suitable for them on an airline.
There can be problems with communications - on a very recent flight to the US (British Airways) only one of my DSs was listed for a children's meal.
The children's meals also leave a lot to be desired - Adult breakfast was a croissant - children's breakfast was fruit salad. I mean, really????
Asian airlines have an Asian option and a Western option - the Asian options are far too spicy for my DC (and really, I can't face the thought of spicy steamed fish with noodles for breakfast as an adult - I rather imagine very few children would stomach it)
I've long since faced the fact that I have to travel with snacks, and just deal with the fact that they will pretty much be carbed out on bread, crackers and biscuits, with some apple juice on the side.
But - they're happy for that to happen. And, as they are getting older (8 and 5 currently) they are gradually getting better.
If I had to deal with additional issues I'm not sure what I would do - not fly?! Never let my DC see their family on the other side of the world?
Sadly - if there was a risk of my children being violent, then that is the choice I would make.
