1. Jet lag
The situation, which is called as jet-lag, is observed when travelling across a number of time zones during prolonged flights from east to west and from west to east. The jet-lag appears with the signs differing from person to person, and results mostly from conflict between body clock and destination time.
Jet-lag is in mild form during the flights from east to west, and it generally does not pose any problems, but it appears especially as weakness, fatigue, anxiety and insomnia during the flights from west to east.
It will be helpful to pay attention to the following issues in order to not to experience this situation during the prolonged flights across the time zones parallel to the equator.
- Sleep well and be well rested before the flight.
- Have some light meal, which will not cause discomfort, before and during the flight.
- Adjust watch, mobile phone and other electronic devices according to the destination time shortly before the flight.
- Having drinks containing caffeine may be preferred in the daytime of the destination country, but these kinds of drinks should be avoided within a period of time of 4-6 hours before sleep time.
- Wear loose and comfortable clothes.
- If any passenger suffers extremely from discomfort of insomnia, will need to consult with a physician for taking sleeping pills.
2. Scuba Diving and Flight
A passenger, who has involved in scuba diving, should not fly for 24 hours after his/her last scuba dive. Since the air pressure in cabin of the aircraft is generally adjusted to an altitude of 5000-8000 feet (1800-2500 m), the air pressure is lower than the air pressure in sea level, and this increases the risk of low pressure sickness which is called decompression sickness. For this reason, passengers who like diving should pay attention to the following:
- Avoid diving in case of any sickness.
- Not to push the safety limits required during diving.
- Not to arrange their flight for at least 12 hours after a single dive, and at least 24 hours after multiple dives.
Passengers who are pregnant should obtain detailed information on the possibility of experiencing any problems by consulting with their physician before the travel. It is important that those passengers should note down and take with them the telephone numbers of their local physician and the doctors, healthcare facilities, emergency health services and ambulance at the destination, against the possibility of any emergency which may occur before during and after the flight.
After the twenty eighth week of their pregnancy, they should submit the report which is obtained from a physician or midwife in the last two weeks, to the representative of Turkish Airlines before the flight , which states that they can travel onboard an aircraft . In this report it’s obligatory to state that,
- The pregnancy is in normal course,
- No complication has been developed,
- The pregnant has no extra risk or sickness,
- Possible due date (the delivery is not expected within 4 weeks after the date of flight),
- There is no inconvenience for the flight.
Turkish Airlines reserves the right of cancellation of the tickets for the passengers, who have entered the 29th week of pregnancy, and who have not submitted the mentioned report.
In a problem-free pregnancy which is in normal course, flight is not allowed at the following circumstances:
- For the multiple pregnancies such as expecting twins or triplets, the flight is not allowed from the end of 32nd week of pregnancy until 7 days after the delivery.
- For the single and problem-free pregnancy which is in normal course, the flight is not allowed from the end of 36th week of pregnancy until 7 days after the delivery.
It is recommended to choose an aisle seat that will give the pregnant passengers comfort and help them to walk around in the aisle for exercising.
Doing exercises periodically, walking around the aisle, wearing varsity socks preventing the blood congestion in the veins and leg swelling, avoiding to wear socks, which may interrupt blood circulation, has importance in terms of protecting themselves against the blood circulation disorder which is called Deep Vein Thrombosis.
Certain countries do not allow the entry of the pregnant women, who are not their own citizens, from their borders. In case of a question regarding this, they should contact with the representative office of the concerned country nearby, before the flight.
