Question : In the next four weeks, what day should you book your trip?
Answer : Since low prices are preferred, look at Mar 20th. As of Feb 20th, it's showing the cheapest ticket sales at $853. That is 56% below the average price for this route, so you can spend that extra money on an adventure rather than the flight.
