Taking a leaf out of Air India's book, People for The Ethical treatment of Animals (PETA) India wrote multiple letters to all the major Indian airline companies, asking them to serve vegan meals to all passengers on-board.

Earlier this week, the government carrier had received a lot of flak for announcing its decision of serving vegetarian meals to domestic economy class passengers. Supporting the idea of providing meat-free food, PETA appealed to all Indian airline companies to serve eco-friendly meals to passengers across all classes. "Balancing an airline's carbon footprint can start with putting meat and dairy products on the no-fly list," said Dr Manilal Valliyate, PETA CEO.
