Every time I land in Chennai I get greeted in English (Welcome to Chennai) / or if I end up traveling within the country and use Air-India (get greeted in Hindi) – which is great. However, it makes a lot of sense to greet first in Tamil (or) whatever the local language of the region is: landing in Hyderabad, (greet in Telugu), Karnataka (Kannada), Gujarat (Gujarati) and more.
This will help in preserving the culture of our State. This will also assist in creating more local jobs. This is nothing new in the rest of the world. You travel to China, Middle East/ anywhere in the world, you get greeted in their local language.
