I will be arriving in India, and my stay in will be in Delhi, where I would be sightseeing and doing the usual touristy things. From Delhi, I am planning to head towards Kerala and would like to stay in a houseboat. I would like to know a few things to help me with the trip from Delhi to Kerala. 1. I would like to know which Kerala airport I should land at, as there is more than one? 2. How long would the Delhi to Kerala flight take?
