When Is The Best Time To Purchase Cheap Airline Tickets

from from Bratu?

Why is it hard to find cheap airline tickets from from Bratu when you’re booking at least a week in advance with some companies? What’s the cheapest way to get from Bratu to Buenos Aires? Should I take this flight or that one? Is there an alternative if they don’t have my preferred carrier on their flights out of Thiruvananthapuram (Trivandrum)?
