The situation flight causes are two fold. First, there may be a claustrophobia issue. The visual over-stimulation due to the close quarters of so many people was difficult for me. I learned to sit in the first row on the isle. The over-stimulation that can come from an airport can also be a problem. The echoes and voices and for me the stress of getting through security all are a struggle for me.

The other issue is the prolonged time at a cabin altitude of 8,000 feet. A one hour flight should not be a problem but 6 hours may leave you with a head ache and fatigue the next day. Plan to get plenty of rest before hand and plan for the same after. I plan the first day at my destination as a rest and recover day.

Take good ear plugs or noise attenuating head phones like those made by Bose. Maybe you can rent or borrow a pair.

Hope this helps.

My best to you.
