How is the in-flight environment different from that of everyday life?
All of our flights maintain a temperature range of 23C to 25C.
To be comfortable, we suggest wearing a long-sleeved top and clothes made of a thin material.
In an aircraft, the relative humidity is usually between 10 to 20%.
You may feel discomfort due to the low humidity as your skin and mucous of your nose, and eyes become dry.
- Keep yourself well hydrated by drinking lots of water, juice or other beverages. Be cautioned that drinking lots of certain liquids, such as coffee and tea, can have the reverse effect and actually cause dehydration.
- Passengers who wear contact lenses can prevent dryness and inflammation of their eyes by removing their contacts and wearing glasses.
- Using supplements and/or water sprays to keep your skin moist is a good practice.
In-Flight Atmospheric Pressure
Our cabin maintains an atmospheric pressure that emulates an altitude of 5,000 to 8,000 feet (1,524 to 2,438 meters) above sea level, with little or no effect on the average healthy person.
- If your ears become deafened or affected by the pressure change upon takeoff or landing, either work your jaw up and down lightly or drink some water. Closing your mouth and holding your nose while blowing out lightly may also be helpful.
- Giving small children something to eat is also recommended.
Cosmic Radiation Exposure
In general, long-distance flights expose passengers to about 0.004 to 0.005 mSv of cosmic radiation, and short-distance flights about 0.001 to 0.003 mSv.
Considering the amount of exposed radiation from a typical X-ray is about 0.02 to 0.04 mSv, cosmic radiation exposure through air travel poses little danger to the human body.
In-Flight Noise Level
Improvements in Korean Air’s soundproof panels and seats have gradually reduced noise levels so that they generally pose no inconvenience. However, during takeoff and landing or in some seats near the engines, you may detect a slight rise in noise levels. Feel free to ask a flight attendant for earplugs.
Please be aware that we cannot prevent passengers from carrying on peanut products. Further, particles from peanuts and tree nuts eaten during the previous flight can remain in the aisles, seats or the cabin air.
As we cannot guarantee an absolute peanut-free environment onboard, we strongly advise passengers with peanut allergy to inform our staff of your medical condition before boarding. You are required to sign the agreement on your travel given the situation described in this notice.
For your safety, please be sure to prepare and carry any prescribed allergy medicine(ex. EpiPen etc) with you.
- Korean Air will do its best to make accommodation for a passenger with animal allergies by moving the passenger to another seat away from the passenger with an accompanying animal. However, please note that the seat change is subject to seat availability and is not guaranteed. We thank you for your understanding.
- Before flying with Korean Air, please consult with your doctor about whether you are fit to travel.
- Please be sure to let the agent know about your animal allergies when reserving your ticket, and be sure to fill out your prescription information when checking in.
- For your safety, please be sure to prepare and carry any prescribed allergy medicine with you. Also, you must be able to perform first aid prescribed by your doctor, and for additional safety, your companion or family members must be able to perform the prescribed first aid as well.
- For security screening reasons, please be sure to bring your doctor’s note which permits you to carry a medical syringe on board for emergency.
