Question : Interested in traveling in the next 30 days and want to get the lowest fare?
Answer : Since low prices are preferred, look at Mar 4th. As of Feb 20th, it's showing the cheapest ticket sales at $442. That is 29% below the average price for this route, so you can spend that extra cash on an adventure rather than the flight.
Question : Are you paying the cheapest or highest price for your ticket to San Salvador?
Answer : Ranging from $442 to $748, prices for JAX to SAL change a lot less than the majority of routes from the United States. However, the sooner you book, the better price you tend to get.
Question : How long do most people visit San Salvador?
Answer : Of course you're not most people, but if you were, you'd stay roughly 10 days.
Question : Is price more important than specific travel days for you?
Answer : Thursday is your lowest-cost day to fly in the month of March. Being flexible with your travel days garners even more savings during booking.
