I've flown a lot. No matter how much, I'm never fully at ease with it.

Before I joined the Military I took up Parachuting. You would think that would have helped, Nope!

My advice, either bring what you think will be the most interesting book you can find. Or.... watch the movie they have. You NEED something that will help distract you.
If by chance you really start to get massive anxiety. Get into the bathroom and wash your face, throw cold water in your face and back of your neck. You need to shock yourself (so to speak) back to reality. Use ice if you have to.

There's not much that can be done other than trying to figure out what you can do to get your mind off of the flight.

Crossword puzzles.... writing a journal, letter, Something!

Good luck.... Oh, Don't eat any sweets at all. From the night before through the flight. Alcohol is Bad too.
Try turkey before you fly. It makes you tired and relaxed.

Applaud yourself for even going on this trip, or shall I say committing to this trip. I can't even think of going a few towns over with out the blanket of fear I'm so used to! Take whenever you need with you and have a plan in case you do freak out.

My heart goes out to you on this one. I use to have to fly when my parents lived over a thousand miles from me and my dad was very sick. I hated flying then and I don't like it now.
To keep the panic away back then (this was about 30 years ago), I use to wear head phones with relaxation CD's playing. They eventually changed where I was not able to use them on take off or landing which is when I needed them most.
No sure if any other player (Ipod?) is allowed during take off and landing as I haven't flown in years.
How bout some search and circle books or crossword puzzles to help distract yourself.
Drink plenty of water to keep from getting dehydrated. No alcohol.....it will make things worse.
Good luck. I am keeping my own feet on the ground.
Gentle ((((((((((Hugs)))))))))))

Make sure to have low caffeine and lots of snacks that day! Give yourself a hand message or whatever calms you down during the flight and chew gum! Also try and smile at anyone you see, the happier you come off the better you will feel. And other people smiling back might help calm your nerves.

Thanks for all the suggestions. I hope I don't just freak out mid take off and need to be taken off the plane. I do have klonopin to take which I was utilize so I can be semi normal before boarding. Ugh. This is gonna be some trip.

I’m sorry you are experiencing some anxiety in regards to your business trip. I understand your panic! I experience all sorts of undesirable emotions when I have to fly. We were stationed in England for four years and the flight there and back was a challenge. Thankfully, my husband and daughter were right beside me. I took a Dramamine because I do get motion sick. It made me drowsy, so I slept most of the way. You could listen to your favorite music, read a book or do crossword puzzles. Do something that occupies your time. If you have things to do for work, bring your computer and work on the plane. Prayer is always my coping tool!! I wish you a safe trip and peace of mind!!
