My 19 year old son sustained a concussion yesterday and will be discharged from the hospital tomorrow.  He had short term memory loss that is vastly improved.  He plans to fly from Minnesota home to Hawaii for Christmas 3 days later.  The doctor says it should be okay.  Your opinion?
Hello and welcome to Chat Doctor. Thanks for your query. I understand that you are concerned about the flight trip for your son following his discharge from the hospital. You have mentioned that he has improved after a concussion that he sustained yesterday. I presume that he has had a detailed evaluation and any serious intracranial causes have been ruled out. If this is the case, then there shouldn't be a problem with his flying. Just ensure that he gets adequate rest and HY Chat Doctor. Wish you all the best.
