Travel light and if you get stressed and shaky at the airport get a wheelchair. Ask yourself what might stress you and find a solution. Go early. I tell the agent at check in that I have PD as I find they are more patient as you drop your ticket, boarding pass, sweater, purse and can't get the credit card out of your wallet to pay baggage fees. Pay to check in second bag if you have one. The lighter your load the easier it is. Some airports have a wooden cane they let you use as you go through metal detector units.
Have fun and just tell yourself, I have PD but I am going on a trip anyway.
Have the best time.
Carry "Facts of Life" with you. This would be a packet that identifies you and your significant others, phone numbers, addresses....who to call in an emergency. List your recent vital signs, medical issues, and medicines you are taking, your doctors. Allergies should be identified. Any other info that an EMT should know about you before treatment. Travel insurance will ease your concern about having to cancel on short notice. Travel insurance is well worth cost. Take a flash light.
Hi, I travel quite a lot as I have an apartment in sunny Spain which gets me away from the rain in Ireland. The most important thing to bring are your meds. I know that's quite obvious but when you are on maybe up to 10 different tablets and you are going for a couple of weeks it takes a good bit of organizing .I am also on the Apomorphine pump and the different pieces are quite bulky. I have no problem with travelling as such. I find the most stressful part is the security checks .My advise is to go early and if there is a fast lane (usually only for domestic flights) ask too be allowed use it.
The Motion all Parkinson's Foundation has these kits called "Aware in Care" so you need to travel with one of those. It has a list of meds plus instructions for hospital staff.
In Tennessee, we have decals that indicate to any first responders that in your glove box is a list of meds, doctors etc.
Always wear a medical bracelet or dog tags with PD on them.
My doctor told me to always carry some medications in "Carryon " luggage and some in main luggage that goes in the hold. I found this an easy arrangement when travelling to Australia from New Zealand.
