As a general rule, try to avoid any unnecessary hectic in the run-up to your departure. Give yourself enough time to get to the airport and check in. If you are suffering from an acute medical condition (such as a heavy cold), ask your doctor if it is advisable for you to fly.
If you want to reduce the effects of jet lag, you could try to start getting into the daily rhythm of the time zone you are flying to a few days before your departure. If you’re travelling west, this means going to bed later and getting up later the next morning. If you’re travelling east, it means going to bed earlier and getting up earlier, too.
If you are suffering from a chronic medical condition – especially one affecting the heart or the lungs – ask the doctor treating you if they consider you fit to fly. You could also ask them to provide you with a medical certificate (in English) stating the diagnosis of your condition, any treatment medication you are receiving and the doctor’s contact details, including a phone number they can be reached at. If you have to take regular medication, we advise you to take 1½ times to twice the amount you expect to need in your carry-on baggage. After all, flights can sometimes get diverted and occasionally suffer substantial delays, even if you are already seated on board.
If you are at a higher risk of developing a deep-vein thrombosis (e.g. if you have already suffered a thrombosis, have a chronic heart or lung condition, are substantially overweight, are pregnant or have recently undergone an operation), we advise you to contact your doctor and discuss taking a blood-thinning agent and/or wearing compression stockings for the flight.
