The cheapest days for air travel are Tuesday and Wednesday. Flights that depart on Thursday and Saturday are also relatively inexpensive as compared to other days of the week.
Travellers make the most savings on airfare by searching for flights early and making bookings one to four months in advance. Sunday and Friday are the most expensive days to fly. Travellers who book long-haul flights to travel on Thursday and return on Monday generally pay 20 percent less than those who travel on Saturday and return on Sunday; however, other factors affect ticket prices, such as the destination, time of the year and ongoing local events.
