Final Words!

Although there is no magic time and day of the week that will guarantee a person the cheapest airfare available, the best time to travel would be mid-week, i.e., Wednesdays, both for domestic and international travel. Weekends, i.e., Saturdays and Sundays, are expensive travel days, although Sundays have good deals available.

Instead of concentrating on the days of the week when one should purchase a plane ticket, one should aim at booking their tickets within an optimal time of one to six months, depending on their travel plans.

It would be best to book domestic travel one or two months in advance, whereas for international travel, one should aim at booking three or five months in advance of their travel date. It should be noted, however, that if one intends to use miles, it is never too early to start checking and booking their travel.
