Frequently asked questions

Is it cheaper to buy a plane ticket from DSD to IAD last minute?
When it comes to booking your flights, it pays to be prepared. While it's possible to pick up a last-minute deal on a DSD to Washington Dulles Intl. Airport (IAD) flight, 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 book a domestic flight is between 28 – 35 days ahead. For international trips it's between three and four months.
