IndiGo, India's largest airline will fill its airport buses at 50 per cent capacity when service resumes. The airline will also discontinue on-board meal services, CEO Ronojoy Dutta said. These along with frequent deep cleaning of aircraft are part of the multiple changes that the airline will do its protocols in order to keep crew and passenger crew safe when the airline starts operating again. Indian aviation regulator DGCA is also framing a set of protocols to ensure that social distancing is measured in confined places like aircraft and airports once air transport resumes. Airlines will have to follow the protocols until the World Health Organization declares the outbreak over which according to the agencyβs own estimate is months away. The protocols include mandating airlines to keep the middle seat and last three rows empty, barring on-board and duty-free sales and boarding only three rows at one time to prevent crowding.
