Just before you feel your stomach rumbling, take a deep breath. Hold your breath for ten seconds, and then breathe out. When you take a deep breath, your diaphragm pushes down on your stomach. When pushed on, the stomach acts like a water balloon and protrudes in the opposite direction. This may help with digestion by mobilizing the stomach contents and also helping air move through to the small intestine. If you are nervous because of a meeting at work or a test at school, you might want to take a trip to the bathroom before the big event. Nervousness and anxiety increases the activity in your gut, so you may have to use the bathroom a little sooner than usual. Your stomach may be telling you that you need to eat. Although eating isn't always the answer to a growling stomach, it will sometimes solve the problem. Since the squeezing of your intestinal tract gets louder when your small intestine is empty, you could turn the volume down by giving it some food to digest.

Check ahead with your airline to see if you can snag a comfortable seat on the flight. Even within the same class and fare, some seats are far superior to others. Consider an aisle or exit row seat for added legroom, or a window if you want to lean against the wall and sleep. Try to avoid seats near the toilets/lavatories, as other passengers will be accessing these regularly.  Bulkhead seats are also a good option if you need extra legroom. These are seats positioned behind dividing walls, screens, or curtains, with no other seats directly in front of them. Remember to never choose an exit row seat if you will have an infant or small child with you, since this could make it more difficult for you to open the exit door in case of an emergency. Some airlines allow you to pay a little extra to get a better seat, even if you aren’t going first class or business class. These options may have names like “Economy Plus” or “Even More Space.” If you’re overwhelmed with luggage, getting comfortable on the plane may be difficult. Check with your airline ahead of time to find out about their check-through and carry-on policies, and bring only the absolute essentials onto the plane with you. One backpack is fine for the plane, and it is easier to find a place in the overhead bins or under the seat for a small backpack than for a larger roller bag.  Many airlines will allow you to bring one carry-on bag per passenger, plus a “personal item” such as a purse or diaper bag. Check with your airline to make sure your carry-on luggage meets their size and weight requirements. Wearing tight or uncomfortable clothing can make a long flight miserable. Dress in loose, cozy clothes and comfortable shoes, and make sure to bring at least one layer (like a sweater or zip-up hoodie) in case it gets cold on the plane. Compression socks or stockings can help improve circulation in your legs and prevent inflammation and blood clots when you have to sit in one position for hours at a time. Trying to sleep in an airplane seat without extra head support can result in lots of frustration and neck pain. Take a travel pillow or head restraint, and try to avoid using the inflatable ones unless you know you will be comfortable.  If you don’t already have a travel pillow, you can purchase one at a shop in most airports. Some airlines offer their own pillows for long flights, but they may charge extra for them. Check ahead of time to find out if your airline provides in-flight pillows and blankets. Since planes can get cold, you may also wish to bring a small throw or travel blanket. Take a hairbrush, toothbrush, lip balm, and anything else that you need to help you freshen up before you land. Facial wipes are also a great for helping you feel clean and refreshed.  Be courteous to your fellow passengers by stepping into the bathroom before you brush your teeth or freshen up your deodorant! Check airport security regulations before packing any liquids or gels in your carry-on luggage. You can safely travel with most liquid or gel products if they are in containers no larger than 3.4 fluid ounces (100 mL).
