Leaving from Detroit (DTW)

Check Washington to Detroit fares — prices on the return direction often move on a different rhythm.
When to book
For a trip of 383 miles, booking 2–4 weeks ahead typically lands you in the sweet spot. Leave it to the final two weeks and prices usually climb as the cheapest seats sell out. If your dates are flexible, midweek departures are where the lower fares hide on most domestic routes.
Good to know before you go
- Basic economy fares often exclude checked bags and seat selection. Price the whole trip, not the headline fare.
- Get to the airport two hours before departure; security, not the flight, is the part that runs late.

- Download the airline's app before you fly; gate changes and delays show up there first.
- Nonstop time on this route is about 1h 17m — a one-stop itinerary needs to be a lot cheaper to be worth the extra hours.
