I have travel plans via air in a particular month where I will be going to and fro between two places. If I book tickets via online travel agency (Yatra/MakeMyTrip), they offer me to get travel insurance. But I have to buy insurance multiple times (for each return trip in my case) increasing my cost.
Can I buy insurance which covers all my air travels for, say, an entire month (within which I have my multiple air travels)? Are there any dos and don'ts that I need to be aware of?
