I read your letter on traveling w/ PD. My mother can't write this as she is traveling. She has level 2 PD and went over 100k miles with work (she is 77 years old). I travel a great deal for work and I see many individuals w/ PD. 1. Allow 1 hour before departure at airport 2. Do not sit by emergency exit 3. TRAVEL LIGHT! There are a number of books on how to have just one case and check it (carry on is difficult for PDers). Please travel (P. S. I work @ MIAMI airport and we like ALL travelers)
