Surviving travel as healthy as possible

Someone recently asked me for suggestions on how to healthily survive a 10-hour flight.
My advice was not good. I told him that I survive international flights with booze and a sleeping pill.
Seriously, here is my advice on how to survive an international flight or even a domestic flight:
Stay hydrated. Drink lots of water before, during and after the flight.
Avoid alcohol before and during the flight. (For the record, I don’t take this advice.)
Take healthy snacks with you: fruit, nuts, peanut butter crackers, pretzels, even a sandwich.
Walk around every once in a while.
If a meal is offered, go with the healthiest option. (Go with the chicken or fish.) You can probably view the menu online for preplanning.
Don’t beat yourself up when you stray and have a drink or don’t have enough water or chow down on something super unhealthy. All we can do is our best. And we do slip up. And hell, most of the time when I travel I am on vacation. And one of the greatest things about going on vacation (especially when traveling somewhere new, exotic, international or just awesome) is the food and drink.
We head to Missouri tomorrow. I am looking forward to some good home cooking and some barbecue. We also will be having an early Thanksgiving celebration with Curt’s parents, his brother and our two nephews. There will be lots of eating and good food.
