Mumbai: Passengers leaving their seats to sit along the aisle, passengers without mask, some roaming aimlessly throughout the cabin, passengers constantly buzzing crew for liquor, hot beverages. These are some of the experiences faced by Air India flight attendants who operated relief flights from Mumbai and Delhi to Frankfurt in the past two days.Following complaints from its crew, Air India on Thursday responded thatv since these flights are “ferrying only screened healthy passengers, there is hardly any chance of infection” . This drew flak.Air India crew has appealed that the foreign embassies that arrange for these relief flights should brief their citizens about precautions to be followed to limit possible contagion.“Passengers should be educated about ways they could contract the infection onboard and ways they could spread it to others. When evacuation flights were operated to Wuhan, pre-packed food and a bottle of water was kept on each seat before passengers boarded.They were told there would be no service on board the flight. The protocol should be followed,’’ said a senior crew member.
