Everyone should try to avoid peak travel months for your desired destination as there is increase of air fares on these periods. I always fly on weekdays or odd hours for cheap airfare deal. I am used to get the best airfare deal from Globester.com with special discount offers. They are specialized in discounted or negotiated air tickets.
The cheapest time of the year to fly to El salvador is from February to March and then again in May, and then from August to October.
spring break
about February =)
when the kids are at school
March
during Ausgust or October
ALL YEAR LONG
There is no such cheapest time of the year. You just has to book well in advance for your flights and you get a best deal. Say almost one or two months in advance and try to fly on Saturday you will get chap air deals.
I think... November
January and February are considered out of season and are generally the lowest cost.
If you want to fly cheap book your seats 6 months earlyer
in august, September, January or march or by may
