As you can see in the image above, there were adequate sanitization measures taken by the airline some of which are: 1. There was a dedicated sanitization staff of the airline which cleaned the aircraft each time the passengers got down. 2. The aircraft was thoroughly cleaned on the inside with sprays, vacuum cleaners, sanitizers etc. This cleaning included the aisle, the hand baggage storage spaces i.e. the overhead bins / compartments, seats and the windows. 3. The airline stewards and hostesses too were wearing fully covered white protection for their own personal safety. 4. For passengers, if you take a close look at the featured image and the image below this answer, you'll see the bluish mask and the face shield that was provided by the airline to the passengers. The white mask in the image, though, is a personal N-95 Mask. The mask given by the airline was a basic one (bluish in color). 5. Hand sanitizers were also provided to the passengers.
