When IAD–DFW has a nonstop, that is usually the cleanest product. One-stop options still appear — they are worth opening only if the USD total is materially lower after you count the extra ground time.
Airports for Washington to Dallas
Both ends are in the United States: Washington Dulles International (IAD) to Dallas/Fort Worth International (DFW). This is not an international itinerary, so the usual domestic bag and ID rules apply at the seller. Alternate metro airports can still beat this pair on price.
