Travel at the cheapest times. Everybody knows that flights change in prices throughout the year- but not many know the basic outline that airline companies follow to guide pricing. Firstly- Fridays and Saturdays are the most expensive days to fly, so its best to do your searches Thursday-Monday or other weekday variations. Secondly- 6 months prior is the prime discount time. The pricing guide usually goes premium prices- 12-6 months, low 6-4 months, peak 3-1 months prior. Good Luck!
