Longhaul flight with Aut/ADHD 10yo

[noideaoffuturenow]

Hi, we're flying with a group travelling for 3 weeks soon. DS is Autistic & has always hated car travel. Not used to bus/train/flights. We've had 1 family holiday in 10 years and the odd city break. We're travelling to Australia with family. Any tips/don't dos anyone could share?

Depending on where you are travelling from, some airports have a quiet/sensory room.

Think about whether boarding/disembarking first/last would help and priority going through security, then contact the airline and airport about this.
