The two bar charts compare the prices of airline tickets between Sydney and Melbourne (top) and from Melbourne to Sydney (bottom) over a two-week period in 2013.
Overall, prices fluctuate throughout both weeks and in both directions, with midweek fares generally lower and pronounced peaks towards the end of the working week. Although the pattern is similar for each route, the highest fares occur on different days in week 1.
In the Sydney-Melbourne chart, prices are at their highest on Monday of week 1 and on Friday of week 2, while midweek days (Tuesday-Thursday) show substantially lower fares. Weekend fares (Saturday and Sunday) lie between the midweek low and the weekday peaks. The Melbourne-Sydney chart reveals a similar picture: a sharp rise occurs on Friday of week 1 (the highest point on this chart), followed by relatively high prices on Saturday. In week 2 the fares are lower overall but again increase toward Friday and the weekend.
To summarise, both routes display a clear midweek trough in prices and a tendency for prices to peak around the end of the working week and at the weekend, although the exact day of the highest fare differs between the two charts in week 1.
