When it comes to booking your flights, being organized pays off. While you may be able to find a deal on an IAD to PSL flight at the last minute, prices usually don't get cheaper as the departure date nears. Based on flight pricing and demand studies in 2022, we have found that the sweet spot to lock in a domestic flight is between 28 – 35 days ahead. For international flights it's three to four months.

From Washington, you can get to Perth via Perth, Scotland (PSL), Dundee Airport (DND) and Edinburgh Airport (EDI).

Use the cash you save when booking your seat with Expedia to experience the city's top attractions, such as Scone Palace and Perth Racecourse.
