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.
If you have this allergy, please be aware that we cannot prevent passengers from carrying on peanut products and eating them while in flight. You should also know that peanut elements from previous flights may remain in the cabin.
