Bringing food to America for my autistic son

[Hohohole]

I'm travelling to Florida for 3 weeks and need to bring my son's safe food with me.
It will mainly be crisps,liga,crackers, biscuits and pasta. Is it ok to bring large quantities of these? And do I have to bring it in my carry on or can it go underneath? I know I can buy these things there but he's very fussy.
Any advice for the journey? He's flown before but only a two hour flight.
Thank you.

Definitely contact the airline and ask for whatever might make your child’s flight easier. Varies from airline to airline and airport to airport in our experience but you would be amazed at what people will do. Jet2 on a charter flight were amazing! BA we’re ok and allowed us to choose seats and boarding order which helped (although be aware they may also move them).

UK understands a sunflower lanyard. US doesn’t. Greece does, France doesn’t. Acceptance of the lanyard seems to go with cultural acceptance of the diagnosis.

Unfortunately for me noise cancelling headphones switched on and off aren’t enough if people are talking. I have to use quite heavy duty ear defenders. It’s annoying having to take two pairs but it’s the only way I’ve managed to cope with things like aeroplanes.

I’ve had a good experience in airports in most places I’ve been. The US were amazing with them as are a lot of European airports. Weirdly Berlin didn’t recognise them, but the staff were generally really nice there anyway. I went to India a while back and they were less recognised there, although again I found airline staff were mostly very understanding.

Sorry, this was in reply to a question asked above but the quote hasn’t been included.

just to clarify - the sunflower lanyard hadn’t been reliably recognised anywhere outside of Uk airports, however it has been recognised in a number of places - LA and Brussels were brilliant, as were JFK and Barcelona. But with non-Uk destinations it still feels a bit luck of the draw. As someone said above, getting better but not 100%

Brilliant thank you everyone, delighted he can bring his liga. He's pre verbal so we will probably use the fast track. We have the lanyard and do pre-clearance in Dublin.
He's a sensory seeker so he will need to move during the day flight. Is it alright to walk up and down the aisles with him a few times?
He isn't loud so won't bother anyone with noise. My mum is in the seat behind him and there is nobody in front so hopefully we won't annoy anyone.
He won't wear headphones at the moment but we are working on it.
I have a jetbox sleeper thing for the night flight home. I'm so nervous.

We usually walk up and down the isle a bit and so long as the crew are not doing food service or something it isn't a problem. We also find the white noise of the plane seems to make him unusually relaxed, so it has never been as bad as I feared. I hope it's the same for you and you have a great trip!

Oh and we get kids melatonin in the US at Target and use that to help with jet lag and sleeping on the plane.

what about something to fiddle with his feet/toes? You used to bake to buy massage rollers (like a ridged rolling pin) but a bobble mat or even a couple of balls in a pillow slip might give his feet some wriggle while seated. The more you do the more he will be able to do so be brave and just keep going places. Take lots of photos both of him places but also from his height view point. They are fabulous for looking back on together.

There are Aldi stores all over Florida now.

Is it alright to walk up and down the aisles with him a few times?

It depends if there is turbulence. If the seat belt signs are on then it is a hard no. Also, as someone else has said, if they are serving food/drinks it might be a problem.
