Ajay Singh, CMD, SpiceJet, has said that flying is currently the safest way to travel and there is no reason to feel that the air inside the cabin can be contaminated. “The air in an aircraft flows from top to bottom, and doesn’t really circulate in the cabin. Once it flows out of the cabin, it goes through HEPA filters which, according to manufacturers, clean 99.99 per cent of all contaminants in the air. Hence, we believe that flying is by far the safest way to travel. In buses, metros and trains, having this kind of pure air is not possible. We are providing a controlled environment with a set of tools and safeguards, making sure that it is the safest mode of travel,” he said while speaking at the GMR webinar recently.
