Korean Air has taken measures to assure its passengers safety and wellbeing in the wake of the spread of the MERS virus.
In a statement on Tuesday, Korean Air said that they have implemented high temperature sterilisation of air supply on all their planes.
The technology, which is provided by manufacturers Boeing and Airbus, is able to filter out particles completely to ensure that the MERS virus does not spread within the aircraft.
During flight, fresh air will flow in through the engines while the air from the inside will be discharged. This occurs every two to three minutes.
The airline also said that it has increased the frequency of sterilisation on all its aircrafts from once a month to once a week. The number of sterilised plans also increase from five plans per day to 20 per day.
The MERS outbreak began on May 20 when a 68-year-old man was diagnosed after returning from a trip to Saudi Arabia.
South Korea's total death toll is at 27 as of Tuesday, the largest outbreak of the virus outside Saudi Arabia.
