My only suggestion would be to try to get an exemption from a doctor. We left our home state 4 months before covid with the intent of flying back to visit all of our family and friends. It’s a 3 day drive, and we have a special needs son. I didn’t know they had exemptions at all but I was informed just recently if you can get a doctors note you can get an exemption from the airline. My son is developmentally delayed (8 yo but more like a toddler, non verbal). He won’t even let anyone near him with one. If you could find a doctor to say he had a sensory disorder or something like that perhaps you could be exempted. I shared via Facebook Fauci saying masks should be permanent and complaining about never being able to fly. I just don’t know how difficult it is to get any exemption for you.
