1) Always carry your prescription medications onboard the aircraft and avoid checking them in with luggage. Bring additional quantities for unexpected delays or re-routing. If you are a diabetic, be sure to bring your insulin and glucometer. You must have a pharmacy label on your insulin that includes your name, or you will not be allowed to bring a syringe or needle on board. If you have asthma, be sure to bring your inhaler and keep well hydrated during the flight (one glass of water per hour of flight, avoid alcohol).

2) If you have a chronic heart or lung disease that requires you to be on oxygen, either constant or intermittent, be sure to inquire with the airline about the oxygen service they have available. Oxygen is booked at the time of reservation and requires your physician to authorize the amount be used during flight. Do not rely on the availability of the airlines' emergency oxygen bottles, as they are in limited supply and reserved for air or medical emergencies. If you show up at the gate without pre-arranging necessary oxygen, you will likely be denied boarding.

3) If you are traveling with significant health problems, notify the airline reservations staff so they can assist in planning your trip. Many airlines have a medical desk that can provide support and specific recommendations to accommodate travelers, such as wheelchair assistance for plane transfers.

4) Drinking excessive alcohol the night before flying or during the flight can contribute to dehydration in the body. The effects of alcohol are greatly enhanced by virtue of cabin altitude.

5) Drink plenty of fluids (one glass of water per hour of flight) to help counteract the low humidity within the aircraft cabin. The longer the flight, the drier the air.

6) If you become ill prior to departure with any of the following symptoms, consider postponing your flight: fever with rash; active vomiting; fever with or without diarrhea; and flu symptoms with active cough.

7) If you have recently had surgery (i.e. abdominal, chest, cranial or fractures requiring casts) or a serious illness, check with your doctor to make sure it is in your best interest to fly.

8) Due to aircraft cabin altitudes of approximately 8,000 feet, a light- headed feeling may occur as a warning that your blood pressure is too low. If you feel light-headed, place your head on your knees until the feeling passes. If it does not subside, inform the cabin crew.

9) Many fainting episodes on flight occur when someone is going to, or leaving the lavatory. If you have been sitting a long time, consider standing by your seat for several minutes prior to walking up the aisle. This will allow you to quickly sit down if you become light- headed.

10) Try to minimize the stress associated with travel. Be flexible and allow plenty of time for added security and check-in. By being prepared and building extra time in your schedule, you can enjoy a more relaxing trip.
