A good sale to/from Washington D.C.

Matrix Airfare Search by ITA Software will price this at $357 (Regular Economy). Use those dates on United should reprice to $257 (Basic Economy) and $357 (Regular Economy).

The $357 fare is a regular economy fare which allows for normal size carry-on and personal item in addition to advance seat assignment.

United also has a $257 fare but that is a Basic Economy fare. United Basic Economy fares do not allow for any advance seat assignments. Rather, your seat assignment will be randomly assigned during check-in. In addition, normal size carry-on that does not fit under the seat is charged a $35 fee each way + applicable gate check fees (but free if you have an United co-branded credit card or if you have United elite status).
