Steer clear of foods that will bother other passengers, such as items with too much crunch or odor. Bring an energy bar or some other meal replacement in case the in-flight meal is a travesty or your flight is delayed. Eat in the airport if you don t want to entrust your airline with your culinary fate. Large airports have the usual variety of fast-food franchises, so pick what you know to be the most healthful. Follow any alcohol or caffeine consumption with plenty of water to avoid becoming dehydrated.
Culinary possibilities open up on long international flights with major carriers.
Call in advance and ask what special meals are available you may be pleasantly surprised. Avoiding MSG is tricky. You can speak to your airline, but don t expect a promise that MSG will be absent from your food. Be wary of vegetarian breakfasts if you want something filling you might get just a banana or juice. Inc. How things get done.
