The airlines industry also began to vary prices based on the departure day and time of flights

and when the tickets were purchased. For example, the cheapest day to fly is Wednesday

with weekends the most expensive days to fly, the first flight of the morning (one that requires

you to get up at 4AM) is cheaper than later flights, and the cheapest time to buy a ticket is

Tuesday at 3 PM with tickets purchased on weekends have the highest prices.
