Frequently asked questions

Is it cheaper to buy a plane ticket from Ronald Reagan Washington National Airport (DCA) to IAD last minute?
Booking your journey from Ronald Reagan Washington National Airport (DCA) to IAD last minute could save you money if you're lucky to find a good deal. However, tickets usually don't get cheaper as the departure date nears. If you hold out, flights could also be booked out or the best seats gone (hello, middle seat!). If you don't want to hedge your bets, book well ahead of when you want to leave. It's worth noting that some of the best deals can be found up to 12 months in advance. If your favorite carrier hasn't released its airfares yet, check back regularly as deals are updated on Expedia constantly.
